MP Excise Constable Memory Based Paper (Held On: 11th and 12th September 2025) (Previous Year Paper)

Concept -

For two points to be equidistant from the origin, their distances from the origin must be the same.

The distance between any point (x₁, x₂) and the origin (�1,�1)Unknown node type: span(�1,�1)Unknown node type: span(�1,�1)Unknown node type: span

(0,0)(0,0)(0,0)

(0,0) is given by the distance formula:

Distance=(�1−0)2+(�1−0)2−−−−−−−−−−−−−−−−−−√=�21+�21−−−−−−−√Distance=(�1−0)2+(�1−0)2−−−−−−−−−−−−−−−−−−√=�21+�21−−−−−−−√Distance=(�1−0)2+(�1−0)2=�12+�12

Distance = (√{(x_1-0)^2+(y_1-0)^2} =√{x_1^2 +y_1^2})

Explanation -

Given one point is (3, 4), the distance of this point from the origin is:

Distance = (√{(3)^2+(4)^2} =√{9+16} = √{25} = 5)

Now, we need to find the value of ���

x for the point (�,1)(�,1)(�,1)

(x,1) to also have a distance of 5 units from the origin.

Using the distance formula again:

Distance = (√{(x)^2+(1)^2} = 5)

Now squaring both side -

⇒ x² + 1 = 25 ⇒ x2 = 24

⇒ x = ± √ 24 = ± 2√ 6

Distance=�2+12−−−−−−−√=Unknown node type: spanDistance=�2+12−−−−−−−√=Unknown node type: spanDistance=�2+12=Unknown node type: span

Hence option(2) is correct.

From the given data,

Slope m = - 3/4 and point (x₁, y₁) = (4, - 3)

The general equation of a line, having a slope m and passing through (x₁ , y₁), is

y – y₁ = m (x – x₁)

⇒ (y – (-3)) = - 3/4 (x – 4)

⇒ (y + 3) = - 3/4 (x – 4)

⇒ 4y + 12 = - 3x + 12

⇒ 3x + 4y = 0

Shortcut Trick

Since the dimensions of the final cylinder are already given, we can directly compute its volume without the hemisphere data.

Volume of Cylinder = π × r² × h

⇒ Volume = 22/7 × (9/2) × (9/2) × 42

⇒ Volume = 22/7 × 81/4 × 42

⇒ Volume = 11 × 81 × 3 = 2673

∴ The correct answer is 2673 cm³.

Alternate Method

Given:

Diameter of the recast cylinder (d) = 9 cm

Radius of the recast cylinder (r) = d ÷ 2 = 9/2 cm = 4.5 cm

Height of the recast cylinder (h) = 42 cm

Formula Used:

Volume of a cylinder = π × r² × h

Hemisphere

Recast

Cylinder

r=4.5

h=42

Calculations:

Although the question mentions a hemisphere, the required geometry to solve the problem (the dimensions of the new cylinder) is entirely available. Hence, we directly evaluate the volume of the cylinder formed.

⇒ Volume = 22/7 × (9/2)² × 42

⇒ Volume = 22/7 × 81/4 × 42

⇒ Volume = 22 × 81/4 × (42 ÷ 7)

⇒ Volume = 22 × 81/4 × 6

⇒ Volume = (22 × 6) ÷ 4 × 81

⇒ Volume = 132/4 × 81

⇒ Volume = 33 × 81

⇒ Volume = 2673 cm³

∴ The correct answer is 2673 cm³.

Additional Information

Principle of Volume Conservation

When a 3D solid is melted and recast or reshaped into another solid, the overall physical volume of the material remains entirely constant (Initial Volume = Final Volume).

Volume of a Right Circular Cylinder

The total volume enclosed within a right circular cylinder is effectively its base area multiplied by its height. The formula is: V = πr²h

Volume of a Hemisphere

A hemisphere represents half of a perfect sphere. For any given radius, its volume follows the geometric formula: V = (2/3)πr³

Given:

Radius of Spherical ball = 3 cm

Radius of Hemisphere = 3/2 cm

Formula Used:

Volume of Sphere = (\frac{4}{3}\times \pi r^3)

Volume of Hemisphere = (\frac{2}{3}\times \pi r^3)

Calculation:

Number of Hemisphere cast from sphere is, x = (Volume of Sphere) / (Volume of Hemisphere)

x = (\frac{\frac{4}{3}\times\pi\times 3^3}{\frac{2}{3}\times\pi\times (\frac{3}{2})^3})  

⇒ 16

∴ Value of x is 16.

Given:

A = {1, 2, 3, 4} and B = {3, 4, 5 ,6}

Concept:

• If A and B are two sets then A ∩ B = {x : x ∈ A and x ∈ B}

Calculation:

We have 

A = {1, 2, 3, 4} and B = {3, 4, 5 ,6}

As we know that, if A and B are two sets then A ∩ B = {x : x ∈ A and x ∈ B}

⇒  A ∩ B = {3, 4}

As we know that, any set which contains a finite number of elements is said to be a finite set.

We can see that A ∩ B contains a finite number of elements

i.e A ∩ B is a finite set.

Hence, option 1 is correct.

Given:

The polynomial p(x) = x2 - √2x + 1.

Concept:

For any given polynomial,

p(x) = ax² + bx + c

If x = m then,

p(m) = am² + bm + c

Solution:

According to the question,

For (x=\sqrt2)

( p(\sqrt2) = (\sqrt2)^2-\sqrt2\sqrt2+1=1)

Hence, option 2 is correct.

Given: 

p(x) = 2x3 - 3x2 - x + 4

Calculation:

Let x = -1

p(-1) =  2(-1)3 - 3(-1)2 - (-1) + 4

p(-1) = - 2 - 3 +1 + 4

p(-1) = 0

Since the remainder of p(-1) = 0 , by factor theorem we can say that g(x) = x + 1 is a factor of p(x) = 2x3 - 3x2 - x + 4.

Hence, option 1 is correct answer.

Given:

The proportion of milk and water in a 105 liters mixture is 3:4. This ratio is changed to 3:5.

Calculation:

Initial ratio of milk to water = 3:4

Total mixture = 105 liters

⇒ Initial quantity of milk = (3/7) × 105

⇒ Initial quantity of milk = 45 liters

⇒ Initial quantity of water = (4/7) × 105

⇒ Initial quantity of water = 60 liters

The new ratio of milk to water = 3:5

The total quantity of milk remains the same = 45 liters

⇒ Let the new total quantity of the mixture be X liters

⇒ (3/8) × X = 45

⇒ X = (45 × 8) / 3

⇒ X = 120 liters

New quantity of water = Total mixture - Quantity of milk

⇒ New quantity of water = 120 - 45

⇒ New quantity of water = 75 liters

Excess water added = New quantity of water - Initial quantity of water

⇒ Excess water added = 75 - 60

⇒ Excess water added = 15 liters

∴ The amount of excess water mixed in the mixture is 15 liters.

Given

2x⁵ + 2x³y³ + 4y⁴ + 5.

Concept

The degree of a polynomial is the highest of the degrees of its individual terms with non-zero coefficients.

Solution

Degree of the polynomial in 2x⁵ = 5

Degree of the polynomial in 2x³y³ = 6

Degree of the polynomial in 4y⁴ = 4

Degree of the polynomial in 5 = 0

Hence, the highest degree is 6

∴ Degree of polynomial = 6

Mistake Points  

One may choose 5 as the correct option due to x⁵ but the correct answer will be 6 as 2x³y³ has the highest power of 6.

Important Points

 The degree of a polynomial is the highest of the degrees of its individual terms with non-zero coefficients. Here for a specific value when x will be equal to y then the equation will be:

2x5 + 2x3y3 + 4y4 + 5

= 2x⁵ + 2x⁶ + 4x⁴ + 5

∴ The degree of the polynomial will be 6

Calculation:

1 crore = 10000000

4 crores = 40000000

4 crores = 400 × 100000

∴ There are 400 hundred thousand are in 4 crores.

Shortcut Trick

Present ratio of X : Y = 4 : 5 and ratio after 6 years = 6 : 7.

Calculate the difference in parts: X (6 − 4) = 2 units and Y (7 − 5) = 2 units.

Since the change in parts is the same, 2 units → 6 years.

Hence, 1 unit → 3 years.

Current age of Y = 5 units × 3 = 15 years.

∴ The correct answer is 15 years.

Alternate Method

Given: The current ratio of X and Y is 4 : 5 and after 6 years, it becomes 6 : 7.

⇒ Let the current ages of X and Y be 4x and 5x respectively.

⇒ After 6 years, age of X = 4x + 6 and age of Y = 5x + 6.

⇒ Ratio after 6 years: (4x + 6) / (5x + 6) = 6 / 7.

⇒ 7 × (4x + 6) = 6 × (5x + 6)

⇒ 28x + 42 = 30x + 36

⇒ 30x − 28x = 42 − 36

⇒ 2x = 6 ⇒ x = 3

⇒ Current age of Y = 5x = 5 × 3 = 15 years.

∴ The correct answer is 15 years.

Additional Information

Constant Age Difference

The numerical difference between the ages of two individuals always remains constant, regardless of how many years pass.

Ratio Balancing Method

If the difference between ratios is not uniform, multiply each ratio by the difference of the other ratio to make the increase in units equal for both persons.

Linear Equation in One Variable

Most age problems can be reduced to a linear equation of the form (ax + n) / (bx + n) = c / d, where n is the number of years passed or preceding.

Given:

The sum of the present ages of a mother and her daughter is 60 years.

Six years ago, mother's age was five times the age of the daughter.

Concept used:

Total = Mean × number of entities

Calculation:

Let the present ages of daughter and mother be x and (60 - x) years respectively. 

Then,

(60 - x) - 6 = 5(x - 6) 

⇒ 54 - x = 5x - 30 

⇒ 6x = 84 

⇒ x = 14. 

∴ Daughter's age after 6 years is 20 years.

Shortcut Trick

When the distance traveled is the same for both speeds, apply the harmonic mean formula.

Average Speed = (2 × S₁ × S₂) ÷ (S₁ + S₂)

Average Speed = (2 × 30 × 45) ÷ (30 + 45) = 2700 ÷ 75 = 36 kmph.

∴ The correct answer is 36 km/h.

Alternate Method

Given:

Speed from A to B (S₁) = 30 km/h

Speed from B to A (S₂) = 45 km/h

Formula Used:

Average Speed = Total Distance ÷ Total Time

Calculations:

⇒ Let the distance between A and B be the LCM of 30 and 45 = 90 km.

⇒ Time taken from A to B (T₁) = 90 ÷ 30 = 3 hours.

⇒ Time taken from B to A (T₂) = 90 ÷ 45 = 2 hours.

⇒ Total Distance = 90 + 90 = 180 km.

⇒ Total Time = 3 + 2 = 5 hours.

⇒ Average Speed = 180 ÷ 5 = 36 km/h.

∴ The correct answer is 36 km/h.

Additional Information

Average Speed for Equal Time

If a person travels at different speeds for equal time intervals, the average speed is the Arithmetic Mean: (S₁ + S₂) ÷ 2.

Relative Speed

When two objects move in opposite directions, relative speed = S₁ + S₂. In the same direction, relative speed = |S₁ − S₂|.

Unit Conversion

To convert km/h to m/s, multiply by 5/18. To convert m/s to km/h, multiply by 18/5.

Shortcut Trick

Let the speeds of the two trains be 2 units and 1 unit respectively.

Length of first train = Speed × Time = 2 × 5 = 10 units.

Length of second train = Speed × Time = 1 × 8 = 8 units.

Relative speed in opposite directions = 2 + 1 = 3 units.

Time to cross each other = Total Length ÷ Relative Speed = (10 + 8) ÷ 3 = 18 ÷ 3 = 6 sec.

∴ The correct answer is 6 sec.

Alternate Method

Given:

Ratio of speeds of two trains = 2 : 1

Time taken by 1st train to cross a standing man = 5 sec

Time taken by 2nd train to cross the same man = 8 sec

Formula Used:

Distance = Speed × Time

Relative Speed (opposite directions) = Sum of speeds = S₁ + S₂

Time to cross = Total Length ÷ Relative Speed

Train 1 (L = 10x)

2x

Man

Train 2 (L = 8x)

x

Crosses in 5s Crosses in 8s

Relative Speed = 2x + x = 3x

Calculations:

⇒ Let the speed of the first train be 2x and the second train be x.

⇒ Length of 1st train (L₁) = Speed × Time = 2x × 5 = 10x

⇒ Length of 2nd train (L₂) = Speed × Time = x × 8 = 8x

⇒ Total distance to be covered to cross each other = L₁ + L₂ = 10x + 8x = 18x

⇒ Relative speed in opposite directions = 2x + x = 3x

⇒ Time taken to cross each other = Total distance ÷ Relative speed

⇒ Time taken = 18x ÷ 3x = 6 sec

∴ The correct answer is 6 sec.

Additional Information

Relative Speed in Opposite Directions

When two bodies move towards each other, their relative speed is the sum of their individual speeds (S₁ + S₂).

Relative Speed in Same Direction

When two bodies move in the same direction, their relative speed is the difference of their individual speeds (S₁ − S₂).

Crossing a Stationary Object

When a train crosses a pole or a stationary man, the distance covered is exactly equal to the length of the train itself.

Crossing Another Train

When two trains cross each other, the total distance covered is always the sum of their lengths (L₁ + L₂), irrespective of their direction of movement.

GIVEN:

Distance = 720 km

Speed = 20 m/s

Starting time = 6 am

Stoppage = 1 hrs 30 min

FORMULA USED:

Speed = Distance/Time

CALCULATION:

20 × 18/5 = 72 km/h

Traveling time = 720/72 = 10 hrs

Total time = 10 + 1.5 = 11.5 hrs

Arrival time = 6 am + 11.5 hrs =  5 : 30 pm

∴ Train will arrive at 5 : 30 pm.

Given : 

Profit = 20%

Discount = 10%

Calculation : 

Now by making SP same,

⇒ 20 unit = 6500

⇒ 1 unit = 325

CP = 15 unit × 325 = 4875

∴ The correct answer is Rs.4875.

Given:

An item is sold for Rs. 2,744

 Profit = 12%

Concept used:

Cost price = selling price - profit

Calculation:

The cost price of the article is,

⇒ 2744 × 100/112

⇒ 2744 × 25/28

= 2450

The selling price to earn 5% profit is 

2450 × 105/100

⇒ 2450 × 21/20

= Rs  2,572.50

  ∴ The correct option is 1

Given:

Expenditure : Saving = 6 : 1

Rahul’s income = Rs.42000

Concept used:

Income = expenditure + saving

Calculation:

Income = Expenditure + savings

⇒ 6 + 1 = 7 units = 42000

⇒ 1 unit = 6000

Expenditure = 6 units = 6 × 6000 = Rs.36000 

∴ The correct answer is Rs.36000.

As we know, vertically opposite angles are equal. Hence, we can consider,

We know that, when a straight line intersects two parallel lines, the consecutive interior angles sum up to 180°

⇒ x + 108° = 180°

⇒ x = 180° – 108°

∴ x is 72°

3x - 4y = -13

If we put x = 5 and y = 7,

(3 × 5) - (4 × 7)

= 15 - 28

= -13

So, (5, 7) satisfies the above equation.

Solution:

2x2 + 7x - 15 = 0

⇒ 2x² + 10x - 3x - 15 = 0

⇒ 2x(x + 5) - 3(x + 5) = 0 

⇒ (2x - 3)(x + 5) = 0

⇒ x = 3/2, -5

Hence, The correct option is 4.

Shortcut Trick

Total Expenditure % = 30% + 25% + 15% + 16% = 86%

Savings % = 100% − 86% = 14%

14% of Salary = ₹42,000

100% (Total Salary) = (42000 ÷ 14) × 100 = 3000 × 100 = ₹3,00,000

∴ The correct answer is ₹3,00,000.

Alternate Method

Given:

House Rent = 30% | Food = 25% | Medical = 15% | Others = 16%

Monthly Savings = ₹42,000

Calculations:

⇒ Total spending = 30 + 25 + 15 + 16 = 86%

⇒ Let total monthly salary be S.

⇒ Savings = S − (86% of S) = 14% of S

⇒ 14/100 × S = 42,000

⇒ S = (42,000 × 100) ÷ 14

⇒ S = 3,000 × 100 = 3,00,000

∴ The correct answer is ₹3,00,000.

Additional Information

Percentage Expenditure

When percentages are given on the total salary, simply add them to find total expenditure. Savings % = 100% − Total Expenditure %.

Remaining Balance Concept

If the question states % of remaining salary, use the successive formula: Final = Initial × (1 − r₁/100) × (1 − r₂/100).

Base Value Calculation

Total Value = (Given Value ÷ Percentage of that Value) × 100.

Given:

If sinθ + cosθ = √2

Formula used:

(sinθ + cosθ)² = sin²θ + cos²θ + 2sinθcosθ

Calculation:

(sinθ + cosθ)² = (√2)²

⇒ sin²θ + cos²θ + 2sinθcosθ = 2

We know that sin²θ + cos²θ = 1

⇒ 1 + 2sinθcosθ = 2

⇒ 2sinθcosθ = 1

⇒ sinθcosθ = 1/2

⇒ 8sinθcosθ = 8 × 1/2 = 4

∴ The correct answer is option (4).

In the figure,

The car’s position changes from B to D and it travelled ‘x’ m;

In ΔACD;

tan 60° = 100/AD

⇒ √3 = 100/AD

⇒ AD = 100/√3 m

In ΔABC;

tan 30° = 100/AB

⇒ 1/√3 = 100/AB

⇒ AB = 100√3 m

∴ x = AB – AD = 100√3 – 100/√3 = 200/√3 = 200√3/3 m

∴ Distance travelled by car during this time = 200√3/3 m

Given:

A  and B can complete a work in 20 days.

B can complete a work in 25 days.

Formula used:

Work done = time × efficiency

Calculation:

LCM of (A + B) and B = 100

Efficiency of A + B = 5

Efficiency of B = 4

Efficiency of A = 1

Time taken by A = 100/1 = 100 days

∴ The correct answer is 100 days.

Given:

There are seven consecutive even numbers.

The largest even number is 40% more than the smallest even number.

Formula used:

Average = (\dfrac{sum \ of \ observation}{number \ of \ observation})

40% = (\dfrac{40}{100}) = (\dfrac{2}{5})

Calculations:

Let the even numbers be a, (a + 2), (a + 4), (a + 6), (a + 8), (a + 10), (a + 12)

Again, (a + 12) = 40% of a + a

⇒ (a + 12) = (\dfrac{2a}{5}) + a

⇒ (a + 12) = (\dfrac{7a}{5})

⇒ 5 × (a + 12) = 7a

⇒ 5a + 60 = 7a

⇒ 60 = 2a

⇒ a = (\dfrac{60}{2}) = 30

∴ The numbers are 30, 32, 34, 36, 38, 40, 42

Required average = (\dfrac{30 + 32 + 34 + 36 + 38 + 40 + 42}{7})

⇒ (\dfrac{252}{7}) = 36

∴ The answer is 36

Given:

The average weight of 3 persons A, B, and C is 60 kg.

When D joins the group, the average weight becomes 65 kg.

E whose weight is 3 kg less than that of D replaces A, the average weight of B, C, D, and E becomes 67 kg.

Concept used:

Total = Average × Number of entities

Calculation:

So, the weight of D  = (65 × 4) - (60 × 3) = 80kg

Then, the weight of E = 80 - 3 = 77kg

According to the question,

77 + (60 × 3 - A) + 80 = 67 × 4

⇒ A = 69

∴ The weight of A  is 69kg.

Given:

one of the roots of quadratic equation 7x2 - 50x + k = 0 is 7

Calculation:

According to the question

On putting x = 7 in 7x2 - 50x + k = 0, we get

⇒ 7(7)² - 50 × 7 + k = 0

⇒ 343 - 350 + k = 0

⇒ k = 350 - 343

⇒ k = 7

∴ The required value of k is 7.

Given:

Men: women  2 ∶ 3.

The average weights of the men = 56 kg

The women in the office = 51 kg,

Calculation:

Let the number of men is 2x so the number of women is 3x

As per the question, 

The average weight of the employees in the office,

⇒ (56 × 2x + 51 × 3x) / (2x + 3x)

⇒ 265x / 5x = 53 kg

∴ The correct option is 3

Shortcut Trick

Equate work: 5 Women × 8 days = 8 Children × 10 days ⇒ 40W = 80C ⇒ 1 Woman = 2 Children.

Convert group to single unit: 2 Women + 4 Children = 2(2 Children) + 4 Children = 8 Children.

Since 8 children complete the work in 10 days, the group of 8 children will also take 10 days.

∴ The correct answer is 10 days.

Alternate Method

Given:

Time taken by 5 women = 8 days

Time taken by 8 children = 10 days

Formula Used:

Total Work = Number of persons × Efficiency × Days

Calculations:

⇒ Efficiency of 1 woman = Group efficiency ÷ Number of women = 10 ÷ 5 = 2 units/day

⇒ Efficiency of 1 child = Group efficiency ÷ Number of children = 8 ÷ 8 = 1 unit/day

⇒ Total efficiency of (2 women + 4 children) = (2 × 2) + (4 × 1)

⇒ Total efficiency = 4 + 4 = 8 units/day

⇒ Number of days required = Total Work ÷ Total Efficiency = 80 ÷ 8 = 10 days

∴ The correct answer is 10 days.

Additional Information

Efficiency and Time Relation

Efficiency is inversely proportional to the time taken. If the efficiency ratio is a:b, the time ratio will be b:a.

Man-Day-Hour Formula

For different groups performing work: (M₁×D₁×H₁)/W₁ = (M₂×D₂×H₂)/W₂, where M=Men, D=Days, H=Hours, and W=Work.

Work and Wages

Wages are always distributed in the ratio of work done, which is equivalent to the ratio of efficiencies if everyone works for the same time.

As, given 21st August 1998 = Friday

So, 21st August 1997 = Thursday as the number of. odd day = 1 (Friday - 1 = Thursday).

On 21st August 1996 = Wednesday as the number of. odd day = 1 

On 21st August 1995 = Monday as the number of. odd day = 2 (As 1996 is a leap year, there will be 29 days in February 1996)

On 21st August 1994 = Sunday as the number of. odd day = 1

Then 21st August to 16th August = 5 days.

So, Sunday - 5 = Tuesday.

Hence, on 16th August 1994, it's Tuesday.

Hence, the correct answer is "Tuesday".

Additional Information

Given:

The hour hand and minute hand of a clock together means the angle between minute hand and hour hand will be 0º.

Lower value of time (H) = 2 and angle ((\theta)) = 0º (As , hands of a clock will be together)

Concept used:

 By formula-

 (Time=H:(H\times5\pm\theta\div60)\times{12\over11})

Calculation:

(=2:(2\times5\pm0\div60)\times{12\over11})

(=2:(10\pm0)\times{12\over11})

(=2:10\times{12\over11})

=(2:{120\over11})

(2:10\frac{{10}}{{11}})

Thus, the correct answer is '(10\frac{{10}}{{11}}) past 2' .

The logic followed here is,

Row wise →

Difference of first and second number  = (\sqrt {Third\ number})

First row:

10 - 6 = 4 ⇒ ( \sqrt{16}) 

Second row,

9 - 3 = 6  ⇒ ( \sqrt{36}) 

Third row,

8 - ? = ( \sqrt{9})

8 - ? = 3

? = 8 - 3 = 5

Hence, the missing term is "5".

The given series is as follows:

 (Left) 734 462 397 354 881 (Right)

 The numbers after arranging in ascending order are as follows

 (Left) 354 397 462 734 881 (Right)

So we can see that after rearranging the number only 881 remain's unchanged.

Hence, the correct answer is "option 1".

The logic follows here is:

If the seventh day of a month is three days before Friday, this means, it is Tuesday.

Therefore, we can say that on the 7^th day of the month, it is Tuesday.

So, the 14^th day of the month will also be Tuesday.

Similarly,

The 21^st day of the month will be Tuesday.

Now, we have to find the day on the 19^th day of the month.

If the 21st day of the month is Tuesday then the19th day of the month is Sunday i.e. two days before Tuesday.

Hence, the correct answer is Sunday.

The pattern followed here is : 

 

Hence, 404 is the correct answer.

The correct answer is Option 4: Reject the offer and inform the police.

Officer qualities:

Given:

K + L means K is the son of L;

K - L means K is the sister of L;

K % L means K is the brother of L

K x L means K is the mother of L,

 

1. D - B + C – A → D is sister of B, B is son of C and C is sister of A.

As, C is sister of A and D is daughter of C, it means D is the niece of A.

2. D + B - C % A → D is son of B, B is sister of C, C is brother of A

As, D is son of B and B, C and C are siblings, D is nephew of A.

Or, D is male and to be niece of A, D must be female, so clearly this option cannot be the answer.

3. D × B - C + A → D is mother of B, B is sister of C, C is son of A

As, D is mother of B and B is sister of C, who is son of A, here D is wife of A.

4. D + B × C – A → D is son of B, B is mother of C, C is sister of A

As, D is son of B and B is mother of C, who is sister of A, here B is mother of A, D and C which means A and D are siblings.

Or, D is male and to be niece of A, D must be female, so clearly this option cannot be the answer.

Hence, ‘D - B + C – A’ shows that D is the niece of A.

The logic followed is:

(Addition of left and right side number) × (Difference between lower and upper number) = Middle number

Figure 1:

⇒ (3 + 4) × (8 - 6) = 7 × 2 = 14 (Middle number)  

Figure 2:

⇒ (6 + 3) × (9 - 2) = 9 × 7 = 63 (Middle number)  

Similarly, 

Figure 3:

⇒ (4 + ?) × (6 - 3) = 36

⇒ (4 + ?) × 3 = 36 

⇒ (4 + ?) = 12

⇒ ? = 12 - 4

? = 8

Hence, the correct answer is "8".

Given Statements:

I. Some mangoes are oranges.

II. Some oranges are grapes.

The possible diagram is:

Conclusions:

I. Some mangoes are grapes → False (No direct relationship given between mangoes and grapes)

II. No oranges are mangoes → False (Some mangoes are oranges)

III. No grape is mango → False (No direct relationship given between mangoes and grapes)

Conclusion I and III are complementary pairs.

Hence, "Either conclusion I or III follows" is the correct answer. 

Additional Information 

The pattern followed is,

Hence, “KK” is the correct answer.

The logic is:

Hence, ‘512’ is the correct answer.

Given: Some people are sitting in a row facing north.

1. Y is sitting fourth to the right of A.

2. Only four people are sitting between Y and Z.

3. B is sitting second to the left of Z.

4. Only one person is sitting between Z and C.

5. X is sitting immediately next to the right of C.

6. X is sitting at one of the ends of the row.

Thus, the final arrangement:

If no other person is sitting in the row, then 13 is the total number of people sitting in the row.

Hence, the correct answer is "13".

The logic followed here is :-

(Top number + left number) - (Bottom number + right number) = Middle number

Figure 1:

= (10 + 12) - (5 + 7)

= 22 - 12

= 10

Figure 2:

= (16 + 11) - (4 + 8)

= 27 - 12

= 15

Figure 3:

= (15 + 9) - (5 + 6)

= 24 - 11

= 13

Hence, the correct answer is "13".

Given: NYD, MXC, LWB, KVA, ? 

The logic followed here is:

Hence, JUZ is the correct answer.

Given statement,

The total strength of the class = 60 

Boys : Girls = 1 : 2

This means 20 boys and 40 girls are there in the class.

The rank of 'boy' from the top is 20th

This means 19 students ahead of the 'boy' and 7 girls ahead of the 'boy'. So 12 are boys.

Total boys = 20 

Ahead of boy = 12

After boy = 20 - 12 - 1 = 7 boys

Hence, "Option (2)" is the correct answer.

The logic followed here is;

Logic: Difference of the top numbers × 4 = Bottom Number.

Now, checking the figures:

 → (6 - 2) × 4 → 4 × 4 = 16.

 → (5 - 4) × 4 → 1 × 4 = 4.

 → (7 - 2) × 4 → 5 × 4 = 20.

 → (5 - 3) × 4 → 2 × 4 = 8.

 → (8 - 5) × 4 → 3 × 4 = 12.

Hence, the correct answer is "Option 4".

Here, we can say the problem is one of mutual

disagreement.

The course of action 1. Taking extreme measures like withdrawing the new recruitment policy just because employees protesting against it won’t help, so this course of action doesn't follow.

The course of action 2. will not follow because it will be very harsh action against the employee who is protesting against the new recruitment policy. It can best be solved by finding a middle path via mutual talks.

Hence, the correct answer is "Neither I nor II follows".

Additional Information

Some rules to solve Statements and Course of action questions must be kept in mind while solving it.

Rule 1. Have an unbiased and neutral mind frame. Individual perception must not be used to judge the course of action to be taken.

Rule 2. The first step should be to identify the root cause of the problem. Once the problem is solved, a logical mindset should be employed to figure out the course of action.

Rule 3. There must be no extremity involved in the course of action.

Rule 4. A course of action must be able to solve, reduce, or minimize the problem given in the situation.

Rule 5. The course of action can be said to solve/reduce the problem when it is an established fact, when it is logically possible and when it is known from experience.

Let’s check each option,

1. SON → can be formed from OBSESSION.

2. BOSS → can be formed from OBSESSION.

3. NOSE → can be formed from OBSESSION.

4. BEST → cannot be formed because there is no ‘T’ in OBSESSION.

Hence, BEST can’t be formed from word OBSESSION.

Here, Anil is 6^th from the top and Sumanth is 18^th from the bottom and Anirudh is 14 ranks below Anil and 15 ranks above Sumanth

On combining the statements, we get,

(Left end is taken on the top and right end are taken on the bottom) 

The number of students in the row are 20 + 33 – 1 = 52

Hence, 52 is the correct answer.

The logic followed here is:

So, 'GOB 24' will complete the series.

Hence, the correct answer is "Option B".

Logic:

Angle = - [(11 / 2)M - 30 H]

where M = minute

H = Hour

For option 1 : M = 0, H = 6

Angle = - [(11/2)0 - 30 x 6]

Angle = - [ -180 ]

Angle = 180 (This will create an angle of 180, hence, this option is correct)

For option 2 : M = 15, H = 9

Angle = - [(11/2)15 - 30 x 9]

This will not create the angle of 180

Similarly we can use this formula on option 3 and 4

Hence, Option 1 is correct answer

Given: Five person M, N, O, P and Q.

O is ahead of only N.

__ > __ > __ > O > N

Only P is standing between M and Q.

Case I: M > P > Q > O > N

Case II: Q > P > M > O > N

Here, P is standing second in the queue.

Hence, the correct answer is "P".

Here the pattern followed in each column is:

1^st number + 2^nd number + 3^rd number = 4^th number.

In column 1 → 1 + 2 + 3 = 6.

In column 2 → 2 + 3 + 4 = 9.

In column 3 → 3 + 4 + 5 = 12.

Similarly,

In column 4 → 4 + 5 + 6 = 15.

Hence, 15 is the correct answer.

Given series: 5, 6, 7, 8, 10, 11, 13, 15, 19

To find: incorrect or wrong term

• The given series is a combination of two different series.
• First series: 5, 7, 10, 13, 19
• 5 + 2 = 7; 7 + 3 = 10; 10 + 4 = 14; 14 + 5 = 19
• in the first series, it should be 14 instead of 13.
• Second series: 6, 8, 11, 15
• 6 + 2 = 8; 8 + 3 = 11; 11 + 4 = 15.

Hence, 13 is placed incorrectly in place of 14.

The logic is:

Similarly,

Hence, ‘20-3-10-3-3-16-21-3’ is the correct answer.

The least possible Venn diagram is:

Conclusions:

I. Some parks are colleges. → Does not follow (As, there is no definite relation between parks and colleges. Hence, false)

II. All hospitals are schools. → Does not follow (As, Some hospitals are schools)

III. No park is a college → Does not follow  (As, there is no definite relation between parks and colleges. Hence, false)

But conclusion I and III forms a complementary pair, so either conclusion I or III follows.

Hence, Either conclusion I or III follows.

Concept:

• Intoxicants, sometimes known as psychoactive drugs, have been employed in religious rites, as well as for therapeutic and recreational purposes.
• There are four groups: hallucinogens, inebriants, hypnotics, stimulants.
• Intoxicants include cocaine, cannabis, charas, hemp, hashish, LSD (lysergic acid diethylamide) etc.

Explanation:

LSD (lysergic acid diethylamide):

• LSD (lysergic acid diethylamide) is a highly strong hallucinogen that was first produced in 1938.
• It is synthetically made from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains.
• LSD interferes with the action of serotonin, a brain chemical.
• Serotonin aids in the regulation of behaviour, mood, senses, and cognition.

​Thus, LSD is a type of drug.

Important Points

LSD can harm the body in a variety of ways, causing issues such as:

• Increased heart rate, blood pressure, breathing rate, and body temperature.
• Sleeplessness, loss of appetite, tremors, and excessive sweating.
• Mental problems, including anxiety, depression, schizophrenia.

The correct answer is Mercury.

Key Points

• At room temperature, Mercury metal remains liquid.
• Mercury is a poor conductor of heat.
• It has low density.
• It has low tensile strength.
• It has a low melting point because of its high intermolecular spaces.
• Mercury, which stays in a liquid state until its temperature drops to -40°.

Additional Information

• Some metals melt at lower temperatures than others.
• Tin becomes liquid at 231.8 ˚C.
• Tungsten has the highest melting point of any metal: 3,422 ˚C.
• Mercury is a heavy, silver-white liquid metal.
• Mercury is also called amalgams.

Important Points

• Properties of metal:
• Ductility
• Malleability
• Hardness
• Brittleness
• Zinc Oxide is also called philosopher wool.

Option 1 is correct:

• Rotavirus vaccine is a vaccine used to protect against rotavirus infections.
• These viruses are the leading cause of severe Diarrhoea among young children.
• It infects and damages the cells that line the small intestine and causes gastroenteritis.
• India unveiled its indigenously developed and manufactured Rotavirus vaccine, 'Rotavac' claimed to be the world''s cheapest at the rate of around Rs 60 per dose and aimed at boosting efforts to deal with diarrhoea that kills up to 80,000 children under 5 every year.

The correct answer is sublimation.

• A mixture of sodium chloride (salt) and ammonium chloride can be separated by sublimation.

Key Points

• Under this phenomenon, solid directly changes to gas or conversion of gas to solid without changing into the liquid state.
• It is a process, however, by which compounds can be purified or mixtures separated and as such can be of value as a single step or as an integral part of a more complex analytical method.
• It is applicable to a range of solids of inorganic or organic origin in a variety of different matrices and can be particularly useful when heat-labile materials are involved.
• As a method of the sample, purification sublimation has been used to produce high-purity materials as analytical standards.
• A specific and common example of sublimation used as a means of purification is the removal of water from heat-labile materials in the process known as freeze-drying.
• As a separation technique, fractional sublimation has been used either to purify samples for analysis by removing undesirable components of the matrix or to remove the analyte from the matrix for subsequent analysis.
• The mixture of sodium chloride and ammonium chloride is white in colour but when heated ammonium chloride can get converted into vapour and sodium chloride remains as it is thus this mixture is separated.
• Ammonium chloride gets converted into hydrogen chloride and ammonia and thus the mixture is separated.

Additional Information

• Filtration- Under this phenomenon, solid particles in a liquid /gaseous fluid are removed by the use of a filter medium that allows the flow of the fluid through membrane /filter paper. Solid particles will get trapped on it.
• Chromatography- It is a process for separating the various components of a mixture. The different components of the mixture pass through the stationary phase at different speeds. Different speeds in phases cause them to separate from one another.
• Distillation- It is a process where the conversion of a liquid into a vapour is subsequently condensed back to liquid form.

The correct answer is Option 3.

Key Points

• The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
• The total energy in a closed system remains constant before and after any transformation.
• When energy changes form, such as from kinetic to potential energy, the overall energy quantity remains unchanged.
• Option 3 is incorrect because it contradicts the conservation principle by stating that the total energy before and after the transformation is not constant.

Additional Information

• First Law of Thermodynamics:
• This law is synonymous with the conservation of energy principle.
• It states that the total energy of an isolated system is constant; energy can be transformed from one form to another but cannot be created or destroyed.
• Forms of Energy:
• Energy exists in various forms such as kinetic, potential, thermal, chemical, electrical, and nuclear energy.
• These forms of energy can transform from one type to another but the total energy remains unchanged in a closed system.
• Energy Transformation:
• Examples include a roller coaster converting potential energy to kinetic energy and vice versa, or a battery converting chemical energy to electrical energy.
• Closed System:
• A closed system is one where no energy enters or leaves the system; the total energy within the system remains constant.

The correct answer is Klinefelter's syndrome - 44 autosomes + XXY

Explanation:

• Down syndrome - 44 autosome + XO: This is incorrect. Down syndrome is characterized by having an extra copy of chromosome 21 (trisomy 21), resulting in 47 chromosomes (45 autosomes + 2 sex chromosomes). The notation for Down syndrome should be 47,XX,+21 or 47,XY,+21 depending on the sex of the individual.
• Klinefelter's syndrome - 44 autosomes + XXY: This is correct. Klinefelter's syndrome is caused by the presence of an extra X chromosome in males, resulting in a 47,XXY karyotype (44 autosomes + XXY). The basic features of this syndrome are infertility and small testicles.
• Erythroblastosis foetalis - X linked: This is incorrect. Erythroblastosis fetalis, also known as hemolytic disease of the newborn, is typically associated with Rh incompatibility between the mother and fetus. It is not linked to the X chromosome.
• Colour blindness - Y linked: This is incorrect. Color blindness, particularly red-green color blindness, is most commonly inherited in an X-linked recessive pattern, not Y-linked.

Concept:

Density is a physical quantity which describes the relationship between the mass of an object and the space it occupies (volume).

Density= (\frac{Mass}{Volume}=\frac{[M L^0T^0]}{[M^0L^3T^0]})

The thus dimensional formula for density is [M L^-3 T⁰]

Explanation:

From the above explanation, we can see that, 

Density is given as (\rho =\frac{m}{v}) and its SI unit is kg/ m³

Therefore, the dimensional formula of density is M L^-3 T⁰.

The correct answer is electrolysis of water.

Key Points

• Electrolysis of Water:
• Electrolysis is the process of using an electric current to drive a non-spontaneous chemical reaction.
• In the case of water, electrolysis involves passing a direct current (DC) through water.
• This causes the water molecules to split into their constituent elements: hydrogen and oxygen gas.
• The reaction occurs at two electrodes: the anode (positive) and the cathode (negative).
• At the anode, water molecules are oxidized, releasing oxygen gas and hydrogen ions (H+).
• At the cathode, hydrogen ions are reduced, forming hydrogen gas.
• The overall reaction is: 2H₂O(l) → 2H₂(g) + O₂(g)
• Electrolysis of water requires an electrolyte (like an acid or a salt) to be present in the water to carry the current. Pure water is a poor conductor of electricity.
• This process is used in various applications, including hydrogen production for fuel cells and other industrial uses.
• Electrolysis is a fundamental electrochemical process.
• It's a key method for producing pure hydrogen.

Additional Information

• Hydrolysis of Water:
• Hydrolysis is a chemical reaction in which water is used to break down a substance.
• While electrolysis of water is a type of reaction involving water, "hydrolysis" usually refers to reactions where water itself is a reactant in the breaking of chemical bonds, not simply being split itself by electricity.
• Hydrolysis can occur under acidic or basic conditions, or with the help of enzymes.
• It does not necessarily involve electricity.
• Examples of hydrolysis include the breakdown of carbohydrates into sugars and the breakdown of proteins into amino acids.
• While related to water, it's a broader term and not specific to the electrically driven splitting of water.
• Atomisation of Water:
• Atomization refers to the process of breaking a liquid into a fine spray of droplets.
• This is typically done mechanically (e.g., using a nozzle) or by using compressed gas.
• Atomization does not involve changing the chemical composition of the water. It is a physical process, not a chemical one.
• It's used in applications like fuel injection in engines, spray painting, and humidification.
• It's a physical process of dispersion, not a chemical change like the decomposition of water into its elements.
• Ionisation of Water:
• Ionization is the process of adding or removing electrons from an atom or molecule to create ions.
• Water undergoes a small degree of autoionization, where it forms hydronium ions (H₃O+) and hydroxide ions (OH-).
• However, this is a spontaneous and reversible process, not driven by electricity like electrolysis.
• Ionization is a fundamental concept in chemistry and physics.
• It plays a role in many chemical reactions and physical phenomena.
• While related to water's properties, it's not the term for the specific process of electrically splitting water into hydrogen and oxygen.

The Correct answer is 1 atmosphere.

Key Points

• The pressure exerted by a 760 mm column of mercury at 0°C is equal to 1 atmosphere.
• 1 atmosphere is a unit of pressure commonly used in physics and chemistry to describe the pressure exerted by the atmosphere at sea level.
• It is equivalent to 101,325 pascals or 101.325 kPa.
• 1 atmosphere is also equivalent to 760 mmHg, meaning the height of a mercury column in a barometer under standard conditions.
• This unit is widely used in various scientific fields to measure and compare pressures, especially in fluid mechanics and gas laws.
• The concept of atmospheric pressure is essential for understanding phenomena like weather patterns, the function of barometers, and the principles of gas laws such as Boyle's and Charles's laws.

Additional Information

• Pascal
• Pascal (Pa) is the SI unit of pressure, defined as one newton per square meter.
• It is often used for smaller pressure measurements, such as in engineering and material science.
• 1 atmosphere is equal to 101,325 pascals.
• Bar
• Bar is another unit of pressure, commonly used in meteorology and oceanography.
• It is equal to 100,000 pascals or approximately 0.987 atmospheres.
• The bar is not an SI unit but is widely used for practical applications.
• Poise
• Poise is a unit of dynamic viscosity, not pressure, commonly used in fluid mechanics.
• It is defined as one dyne-second per square centimeter.
• This unit is used to measure the viscosity of liquids, such as oil or syrup.

The correct answer is Oxalic acid.

Key Points

• Oxalic acid is a chemical compound that occurs naturally in almost every plant to some degree, including fruit, vegetable and grain plants.
• Tomato contains more than 10 types of acids such as citric acid, malic acid, ascorbic acid, and oxalic acid etc.
• Oxalic acid content of tomatoes is about 50 mg per 100 g serving.

Additional Information 

Some natural sources of acid:

The correct answer is Vector.

Key Points

• A vector is a biological tool in rDNA technology.
• It is used for the delivery of desired foreign DNA into the host cell.
• A vector is a DNA molecule that has the ability to replicate autonomously in the host cell and into which DNA fragment to be cloned.

 

• Properties of an ideal vector:
• It should be replicate autonomously.
• A vector should be less than 10 KB in size.
• It should be easily isolated and purified.
• It should be easily introduced into the host cell.
• It should have suitable marker genes.
• The vector should consist of unique target sites and recognition sites for various restriction enzymes.
• It should have the capability to incorporate either itself or the DNA insert in the Genome of the host cell.

Important Points

• Transfer RNA (tRNA) is a small RNA molecule that is essential for protein synthesis.
• Transfer RNAs (tRNAs) are molecules that act as temporary carriers of amino acids, bringing the appropriate amino acids to the ribosome based on the nucleotide sequence of the messenger RNA (mRNA). In this way, they serve as bridges between nucleotide and amino acid sequences.

The correct answer is Sunlight.

Key Points

• Sunlight is the most natural and cost-free source of Vitamin D. Ultraviolet B (UVB) rays from sunlight trigger Vitamin D synthesis in the skin.
• Vitamin D produced from sunlight exposure is stored in the liver and fat tissue, where it can be utilized by the body when required.
• Regular exposure to sunlight for about 10-30 minutes (depending on skin type, geographic location, and time of day) is sufficient to meet the daily Vitamin D requirement for most individuals.
• Unlike dietary sources, sunlight does not involve any monetary cost, making it the cheapest and most accessible source of Vitamin D.
• Deficiency of Vitamin D is common in regions with limited sunlight exposure or during winter months, underscoring the importance of sunlight for maintaining optimal levels.

Additional Information

• Vitamin D:
• Vitamin D is a fat-soluble vitamin essential for calcium absorption, bone health, and immune function.
• The two main forms are Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol), with D3 being more effective in raising blood levels of the vitamin.
• Sources of Vitamin D:
• Natural sources include sunlight, fatty fish (like salmon, mackerel, and sardines), egg yolks, and fortified foods such as milk, cereals, and orange juice.
• Vitamin D supplements are widely available for individuals unable to meet their requirements through sunlight or diet.
• Health Benefits of Vitamin D:
• Supports strong and healthy bones by promoting calcium and phosphorus absorption.
• Plays a critical role in immune system regulation and reducing inflammation.
• May help reduce the risk of chronic diseases such as osteoporosis, cardiovascular issues, and certain cancers.
• Risk Factors for Deficiency:
• Limited sunlight exposure, use of sunscreen, darker skin pigmentation, and aging reduce the skin’s ability to synthesize Vitamin D.
• Individuals with malabsorption conditions (e.g., Crohn’s disease) or those following strict vegetarian/vegan diets may also be at risk.

Concept:

Life Cycle of Silkworm: 

• Stage 1:The cycle starts when female silk moth lays eggs.
• Stage 2: The caterpillar of larvae is hatched from the eggs of the silkmoth and they feed on mulberry leaves and consume a large amount of these leaves for around 30 days.
• Stage 3::The silkworm spin a protective cocoon around itself.it is the size of a small cotton ball and is made of a single thread of silk.
• Stage 4: Then Pupa changes into an adult moth. The female moth lays eggs after mating and thus the life cycle of silkworm begins again.

Explanation:

• Silk is extracted from the cocoon that is spun by the pupa.
• The word caterpillar is applied to the larval stages of all species in the insect.
• "Silkworms" are the caterpillars of a particular species of a moth: namely Bombyx mori.
• Silkworm is the larval stage of silk moth and is a more specific term whereas, the caterpillar is a broad term representing the larval stage of any lepidopteran insect.​​

The correct option is generator.

When Tansen sang Raga Deepak, all of the lamps simultaneously lit up!
• Tansen also performed other miracles, such as bringing rain by singing Raga Megh Malhar. According to legend, Tansen used this particular raga shortly after Raga Deepak. This is due to the fact that Raga Deepak raised the temperature while Raga Megh Malhar lowered it. Raga Deepak has been lost to time, however Raga Megh Malhar is still in existence now.
• Tansen was renowned for using music to communicate with animals. A ferocious elephant is supposed to have once been brought into Akbar's court.

Important Note: We are asked to find the weight of the object with a mass of 12 Kg, on moon. It will not be the same, as weight is dependent on acceleration due to gravity.

Concept:

• Mass of the body: Mass of the body is the measure of the amount of substance present in the body.
• The mass of the body is the same throughout the universe.
• Weight of the body: The force of gravity acting on the body is called weight of the body.
• The weight of the body is obtained by multiplying the mass by the acceleration due to gravity.
• It is measured in Newton or Kg Wt

W = mg

• Acceleration due to gravity (g): The acceleration by which an object falls on earth under influence of the gravity of the earth is called acceleration due to gravity.
• The value of g depends upon mass of the planet and its radius.

(g = \frac{GM}{R^2})

The value of g on earth is g = 9.8 m s ^-2. 

Calculation:

Acceleration due to gravity on the moon is 1 / 6 th of that of earth. 

So, the weight of the body on the moon is 1 / 6 th of that of earth. But, mass remains the same.

So mass of body = 12 kg

g = 9.8 m s-2

g of moon

(g' = \frac{ 9.8}{6})

Weight of the body on moon  = mg'

W' = (mg' = 12\times \frac{ 9.8}{6} = 19.6 \ Newton)

So the correct option is 19.6

The correct answer is ​Solar energy is converted into chemical energy

Key Points

• Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
• Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight.
• Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.
• During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green.

Additional Information

• While there are many steps behind the process of photosynthesis, it can be broken down into two major stages: light-dependent reactions and light-independent reactions.
• The light-dependent reaction takes place within the thylakoid membrane and requires a steady stream of sunlight, hence the name light-dependent reaction.
• The chlorophyll absorbs energy from the light waves, which is converted into chemical energy in the form of the molecules ATP and NADPH.
• The light-independent stage, also known as the Calvin Cycle, takes place in the stroma, the space between the thylakoid membranes and the chloroplast membranes, and does not require light, hence the name light-independent reaction.
