Statements:

All sparrows are peacocks.

Some peacocks are birds.

Venn diagram:

Conclusions:

I. All birds are sparrows: This does not follow → As because all sparrows are peacocks and only some peacocks are birds, there is no direct connection between birds and sparrows, so it is not possible that all birds are sparrows. {It is a doubtful positive statement}

II. Some sparrows are not birds: This also does not follow → As because all sparrows are peacocks and only some peacocks are birds, so some sparrows can be birds. {It is a doubtful negative statement}

The pattern in the given series is:

Logic: (Sum of all the digits of first term) × 4 = Second term

Let's apply the pattern:

7689 : 120 :: 6178 : 88 :: 3284 : ?

(Sum of all the digits of first term) × 4 = Second term

(7 + 6 + 8 + 9) × 4 = 120 

30 × 4 = 120 

120 = 120 

7689 : 120 :: 6178 : 88 :: 3284 : ?

(Sum of all the digits of first term) × 4 = Second term

(6 + 1 + 7 + 8) × 4 = 88 

 22 × 4 = 88 

88 = 88

7689 : 120 :: 6178 : 88 :: 3284 : ?

(Sum of all the digits of first term) × 4 = Second term

68 = Second term

Hence the correct answer is 68.

Given: p _ r _ p o _ p o r b _ o _ p o r b _ o r

Let's check each option:

1)  o b p p o p → p o r b p o p - p o r b p o o - p o r b p o r

2)  o b o p r p → p o r b p o o - p o r b p o r - p o r b p o r

3. o b r p r o  → p o r b p o r - p o r b p o r - p o r b o o r

4) o b r p r p → p o r b p o r - p o r b p o r - p o r b p o r

So, In option 4 "p o r b p o r" is repeating itself.

Hence, ‘o b r p r p’ is the correct answer.

The mathematical operation used is:

Logic: Sum of all the digits of first number = Second number

Logic: (First term ÷ 2) + (Second ÷ 3) = Third term

Let's apply the pattern in each row:

First row: 32, 51, 33

(First term ÷ 2) + (Second ÷ 3) = Third term

(32 ÷ 2) + (51 ÷ 3) = 33

16 + 17 = 33

33 = 33

Second row: 28, 33, 25

(First term ÷ 2) + (Second ÷ 3) = Third term

(28 ÷ 2) + (33 ÷ 3) = 25

14 + 11 = 25

25 = 25

Third row: 16, 27, ?

(First term ÷ 2) + (Second ÷ 3) = Third term

(16 ÷ 2) + (27 ÷ 3) = Third term

8 + 9 = Third term

17 = Third term

Hence the correct answer is 17.

GIVEN:

Difference between discount and successive discounts on bill = Rs.22

FORMULA USED:

S.P. = ( 1 - d1/100) × ( 1 - d2/100) × M.P. 

Where S.P. = Selling price, M.P. = Marked price , d1 and d2 = successive discounts % respectively

Discount = ( M.P. - S.P.) 

Discount% = ( Discount/M.P.) × 100

CALCULATION:

Let us assume Marked price be Rs.100

Here , we have discount % = 35

Discount % = (Discount / M.P.) × 100  

⇒ 35 = ( Discount/100)× 100

Discount = Rs. 35.

Now,  we have d1 = 20% , d2 =20%

S.P. = ( 1 - 20/100) × ( 1 - 20/100) × 100 

⇒ ( 1 - 1/5) × (1 - 1/5) × 100 

S.P. = 4/5 × 4/5 × 100 = Rs. 64.

Hence, Discount = ( M.P.- S.P.) = ( 100 - 64) = Rs. 36.

Now, Difference = ( 36 -35) = Rs. 1.

But According to the given question the Difference = Rs. 22.

Hence,

⇒ 1 unit = Rs. 22 

⇒ 100 = Rs. 2,200.

Hence, the amount of the bill is Rs. 2,200.

GIVEN:

Riya  runs 3/2 times as fast as Prerna.

Riya  gives a lead of 100m.

FORMULA USED:

Speed = Distance/Time.

CALCULATION:

 Riya  runs 3/2 times as fast as Prerna.

Riya = 3/2  Prerna.

Riya/Prerna = 3/2.

So, the ratio  of speeds of Riya and Prerna =  3 : 2 

Let the speed be 3x and 2x

Let the distance covered by Prerna be 'L' 

Then , distance covered by Riya  = 'L' + 100

Since, they both will meet , hence time is same.

⇒ L /2x =( L+100) /3x 

⇒ 3L = 2L  + 200 

⇒ L = 200 m.

Riya will cover the distance = ( 200 +100) = 300m.

Hence, Riya has to run 300m before meet.

Shortcut TrickCalculation:

If time is constant, then

Ratio of speed = Ratio of distance

Ratio of speed = 3 : 2

Ratio of distance = 3 : 2

So,

1 unit = 100 m

3 units = 300 m

∴ The correct answer is 300 m.

Given:

50% of [6 – {15 – [6 + 8 ÷ (5 – 3)] + 2}]

Calculation:

⇒ 50% of [6 – {15 – [6 + 8 ÷ (5 – 3)] + 2}]

⇒ 50% of [6 – {15 – [6 + 8 ÷ 2] + 2}]

⇒ 50% of [6 – {15 – 10 + 2}]

⇒ 50% of [6 – 7] = 50% of (–1)

⇒ $\frac{50}{100}$× - 1= - 0.5

∴ The simplified value of the expression is –0.5

GIVEN:

Total income of Mr. X = Rs. 120000.

CALCULATION:

According to the given question, spending on transport = 30°

⇒ 360° =  Rs. 120000

⇒  30° = $\frac{120000}{360^\circ}$ × 30° = Rs. 10,000.

∴ Mr. X has to pay Rs. 10,000 for the transport.

GIVEN:

Discount = 30% 

FORMULA USED:

Profit = (S.P. - C.P.)

Where S.P. = Selling price, C.P. = Cost price

Profit% = (Profit/C.P.) × 100 

CALCULATION:

Let the Marked price be Rs100.

30% Discount on marked price =( 30/100 )× 100 = Rs30.

Hence, Discount  = Rs30.

Now, C.P. of retailer = S.P of company  = ( M.P. - Discount )

⇒ (100 - 30) = Rs 70.

Now, According to the given Question ,

S.P. of retailer = M.P. 

Hence, S.P. of retailer = Rs100.  and C.P. = Rs70.

Hence, Profit = (S.P.- C.P.) = (100 -70) = Rs30.

⇒ Profit% = (Profit/C.P.) × 100

⇒ ( 30/70) × 100 = (300/7) %  = $42 \frac{6}{7}$ %.

∴ Profit% is  $42\frac{6}{7}$ %.

GIVEN:

S.P. = Rs 1,326.

Discount % = 15%

FORMULA USED:

Discount% = (Discount/M.P.) × 100

S.P. = ( M.P.- Discount) 

CALCULATION:

Let the Marked price be X

Now, as Discount% = 15 

⇒ Discount% = ( Discount/M.P.) × 100 

⇒ 15 =( Discount/ X ) × 100 

⇒ (15 × X ) /100 = Discount 

Discount = 0.15 X 

Now, S.P. = Rs 1326

⇒ MP. = ( discount + S.P.) 

⇒ x = 0.15 X + 1326

⇒ 0.85 X = 1326 

⇒ X =  1560.

Hence, Marked price of the article is Rs.1,560.

Shortcut TrickCalculation:

Discount = 15 %

So M.P = (1326/85) × 100 

⇒ M.P = Rs. 1560

∴ The correct answer is Rs. 1560.

GIVEN:

( x +2) and ( x-3) are the factors of x2 + k1x + k2

CONCEPT USED:

If (x -a) is a factor of the equation then 'a' is the root of that equation.

CALCULATION:

It is given that (x +2) and ( x -3) are the factors of the equation that means root of the equations are -2 and 3.

Now, on putting the value of the roots  we will get two equations as follows:

⇒ (- 2)² + k₁ ( -2) + k₂ = 0 ------( 1)

⇒ (3)² + k₁ (3) + k₂ = 0 -------(2)

On solving these two equations we get,

⇒ 4  - 2k₁ + k₂ = 0.

⇒ 9 + 3k₁ + k₂ = 0.

Hence, we get k₁ = -1 and k₂ = -6 .

Hence, the value of k₁ = -1 and k₂ = -6.

Alternate MethodConcept used:

Basic form of a quadratic equation = ax² + (α + β)x + α β

Where α and β are the roots of the equation.

Calculation:

(x + 2) and (x − 3) are the two roots of the given equation.

So, the two roots α = - 2 and β = 3

Now, x2 + k1x + k2

-k₁ = (α + β) = (-2 + 3) =  1

k1 =  -1

k 2 = (α × β) = (-2 × 3) = - 6

∴ The correct answer is option 2.

GIVEN:

Radius  = 14 cm

Height = 48 cm

FORMULA USED:

Volume = 1/3 × πr²h .

When  the cone is cut in between, then ratio of volume of smaller cone to the bigger one = ratio of cubes of their heights or radii.

CALCULATION:

 As cross- section is made from mid- point 

Hence, two cones are formed i.e. cone APD ,which is a smaller  cone

And cone ABC ,  which is a bigger one.

Let the height of smaller cone be h and that of bigger one be H

Volume of bigger cone = 1/3 × πr2 × H  .

Here, r = 14 cm, H = 48 cm

Volume = 1/3 × 22/7 × (14)² × 48 = 9856 cm³.

Now, as cone is cut from mid its  height for smaller cone = 48/2 = 24 cm

Volume of smaller cone : Volume of bigger cone = h³ : H³

Volume of smaller cone : (24)³ : (48)³

Volume of smaller cone = ( 13824 /110592) × 9856 =  1232 cm³

Hence, volume of  the upper portion is 1232 cm³.

GIVEN:

C.I. for 2 years = Rs300   

S.I. for 2 years = Rs250.

Where C.I. = Compound Interest  , S.I. = Simple interest 

Concept Used:

Difference between C.I. and S.I. for 2 years = $(CI - SI)\over(SI of one year)$ × 100

CALCULATION:

S.I. for 2 years = Rs250 

Hence, S.I. for 1 year = 250/2 = Rs125.

Now, C.I. for 2 years = Rs300.

Difference between C.I. and S.I. for 2 years = ( 300 -250) = Rs50.

Hence, Required Rate of  Interest =( 50/ 125 ) × 100 = 40%.

∴ The required rate of interest is 40%.

Shortcut Trick

Divisibility by 15 requires divisibility by both 3 and 5.

For divisibility by 5, the last digit 'a' must be 0 or 5.

To maximize (a + b), we pick the largest 'a', so a = 5.

Sum of digits = 1 + 4 + 3 + b + 2 + 0 + 3 + 5 = 18 + b.

For divisibility by 3, (18 + b) must be a multiple of 3; the largest digit 'b' is 9.

Greatest (a + b) = 5 + 9 = 14.

∴ The correct answer is 14.

Alternate Method

Given 8-digit number: 143b203a

Condition: Divisible by 15 (i.e., divisible by 3 and 5).

⇒ Divisibility by 5: Last digit 'a' must be 0 or 5.

⇒ Divisibility by 3: Sum of digits = (1 + 4 + 3 + b + 2 + 0 + 3 + a) = (13 + a + b) must be divisible by 3.

⇒ Case 1: If a = 5 (largest possible last digit):

⇒ Sum = 13 + 5 + b = 18 + b.

⇒ For (18 + b) to be divisible by 3, possible values for b are 0, 3, 6, 9.

⇒ Maximum value of b = 9. So, (a + b) = 5 + 9 = 14.

⇒ Case 2: If a = 0:

⇒ Sum = 13 + 0 + b = 13 + b.

⇒ For (13 + b) to be divisible by 3, possible values for b are 2, 5, 8.

⇒ Maximum value of b = 8. So, (a + b) = 0 + 8 = 8.

⇒ Comparing Case 1 and Case 2, the greatest possible value of (a + b) is 14.

∴ The correct answer is 14.

Additional Information

GIVEN:

AB = BC = CD 

A to B speed = 5km/h

B to C speed = 10 km/h

C to D speed = 15 km/h

FORMULA USED :

Average speed = Total distance covered/ Total time taken.

Distance = Speed × Time

CALCULATION:

Here , AB = BC = CD  = x 

Now, Time to travel A to B =  Distance/ Speed = x/5 h.

⇒  Time to travel B to C = x/ 10 h.

⇒ Time to travel C to D = x/15 h

Now, Total Distance travelled = AB + BC + CD = ( x + x + x) = 3x.km

Total Time taken = ( x/5 + x/10 +x/15) = 11x/30 hours

⇒ Average Speed = Total Distance / Total time = 3x/( 11x /30) = ( 3x × 30/11x) = 90/11 km/h = $8 \frac{2}{11}$ km/h

Hence, the Average Speed is $8 \frac{2}{11}$ km/h.

GIVEN:

Total runs = 956 

P: Q = 16 :17 ,  Q:R = 15:16.

CALCULATION:

Here

P: Q = 16:17 ...............(1)

Q: R   = 15 :16...............(2)

Now, to make Q equal in both the equations multiply (1) by 15 and (2) by 17  we get,

P :Q = ( 16 × 15) : ( 17 × 15)  = 240 : 255

Q :R = (15 × 17) : ( 16 × 17) =  255 :   272

Now,  P:Q :R = 240 : 255 : 272 

Let  runs secured by P = 240x , Q = 255x , R = 272x 

Now , According to the Question ,

 ⇒ 240x + 255x + 272x = 956 

⇒767 x = 956 

⇒ x = 1.246 

Now, Runs secured by R = 272x = 272 × 1.246 = 338.912 ≈ 339.

Hence, Runs secured by R is  339.

GIVEN:

Different types of scooters produced by a company in first 6 months of 1992.

CALCULATION:

Types of scooters produced  in the month of  May 

x = 20, y = 30, z = 30 , T = 30

Types of scooter produced in the month of January ,

x = 25 , y = 25 , z = 25 , T = 25

Types of scooter produced  in March,

x = 18, y = 50 ,z = 15 T = 25.

Types of scooter produced in June, 

x = 15, y = 20 , z = 20 , T = 35

As, x = y = z = T = 25 i.e. company produced same no. of scooters in January.

Hence, same number of scooters are produced in the month of January.

Shortcut Trick

Weight of new man = Weight of replaced man + (Total members × Increase in average)

⇒ Weight of new man = 65 + (8 × 1.5)

⇒ Weight of new man = 65 + 12

⇒ Weight of new man = 77 kg

∴ The correct answer is 77 kg.

Alternate Method

Given:

⇒ Number of men = 8

⇒ Weight of replaced man = 65 kg

⇒ Increase in average weight = 1.5 kg

Calculations:

⇒ Total increase in weight = Number of men × Increase in average

⇒ Total increase = 8 × 1.5 = 12 kg

⇒ Weight of new man = Weight of replaced man + Total increase

⇒ Weight of new man = 65 + 12 = 77 kg

∴ The correct answer is 77 kg.

Additional Information

Average Weight Formula

Average = (Sum of observations) ÷ (Number of observations). When one person is replaced, the change in sum equals the difference between the new and old person's weight.

Replacement Case (Decrease)

If the average decreases, the new person's weight = Old weight − (Total members × Decrease in average).

Weighted Average

When two groups are combined, the new average = (n₁x₁ + n₂x₂) ÷ (n₁ + n₂).

1GIVEN:

k + (1/k) = 2 

CALCULATION:

We have, 

k + (1/ k) = 2

⇒ $(k ^2 + 1 )\over k$  = 2  

⇒   $k^2$ - 2k + 1 = 0.

⇒ $k^2$ -k -k  +1 = 0.

⇒ k ( k -1) - ( k -1) =0.

⇒ ( k -1) ( k -1) = 0. 

Hence, k = 1

Now ,

8 k× k × k = 8 × 1 × 1 × 1 = 8.

Hence, the required value is 8.

Shortcut TrickCalculation:

k + (1/k) = 2

If we put k = 1, then it satisfies the equation

So k = 1

Now, 

8k × k × k = 8 × 1 = 8

∴ The correct answer is 8.

GIVEN:

Rate of increment = 5%

Present population = 18522

FORMULA USED:

Present Population  = P × $( 100 +R )^t\over 100$

Where P = initial  Population , t = time in years R = Rate of increment .

CALCULATION :

Here t = 3 years R = 5%  Present population = 18522

⇒ 18522 =  P × $( 100 +5)^3\over 100$ 

⇒ 18522 = P × 105/100 × 105/100 × 105/100

⇒ P =  16,000.

Hence, population of village 3 years ago was 16,000.

GIVEN:

15 boys earn Rs900 in 5 days.

FORMULA USED:

 M1 × D1 × W2 =  M2 × D2 × W1

Where M1, M2 = no. of persons respectively

D1, D2 = No. of days respectively

W1, W2 = Wages earn respectively

CALCULATIONS:

Here , we have

M1 = 15 . D1 = 5 , W1 = 900 

M2 = 20 , D2 = 7 , W2 = ?

⇒ M1 × D1 × W2 = M2 × D2 × W1 

⇒ 15 × 5 × W2 =  20 × 7 × 900 

⇒ W2 = Rs1680.

Hence, 20 boys will earn Rs1,680 in 7 days.

GIVEN:

Diameters = AB and CD 

Diameters are perpendicular to each other.

CONCEPT USED:

Diameters are perpendicular = they make 90 degree angle with each other

Radius = Diameter/2  and radius of the circle are always equal.

In a right angled triangle ,

H² = P² + B² 

Where, H = Hypotenuse, P = perpendicular, B = Base.

CALCULATIONS :

Now, we are given a circle with centre O and two perpendicular diameters AB and CD respectively.

We , need to find the length of chord i.e. AC 

We have the following corresponding figure as following,

 

Since AB = CD    ( Diameters of the same circle are equal )

Also, ∠ AOC = 90° and AO = AB/2   

Here AO = OC  ( As both are radius)

Now, Join A and C, so that Right triangle AOC is formed.

Now, in triangle AOC with ∠ AOC = 90 degree

AC² = OA² + OC²

⇒ AC² = OA² + OA²

⇒ AC² = (AB/2)² + (AB/2)²

⇒ AC² = AB²/2   

⇒ AC = $AB\over \sqrt2$

Hence, Length of the chord is $AB\over \sqrt2$.

GIVEN:

Company expenditure increases  first = 25%

again increases = 30%

further decreases = 20%

FORMULA USED:

% change = ( Final value - Initial value)/ Initial value × 100.

CALCULATION:

Let the initial expenditure be Rs100

Now, condition first, increment of 25%

Hence,  ( 100 +  100 × 25/100) = 125.

Now, again increment of 30%

Hence, ( 125 + 125 × 30/100) = 162.5

Now, further decrement of  20 %

Hence, ( 162.5  - 162.5 × 20/100) = 130.

Hence, Initial expenditure = Rs100

Final expenditure   = Rs130

⇒ Overall % change = ( 130 -100)/100 × 100 = ( 130 -100) = 30%

Hence, overall percentage is 30.

Alternate MethodCalculation:

So,

Overall % change = (3/10) × 100 = 30%

∴ The correct answer is 30%.

GIVEN:

Maximum marks in each subject = 100.

FORMULA USED:

Average = Sum of values/ Number of values.

CALCULATION:

Sum of marks obtained by six students in Physics = ( 85 + 75 + 80 + 90 + 95 + 90) =  515.

 Total number of students = 6 

Average =( 515/ 6 )  = 85.83.

Sum of marks in Chemistry = ( 90 + 75 + 60 + 85 + 90 + 90)=  490.

Total number of students = 6

Average = 490/6 = 81.67

If a + b + c = 0, then a³ + b³ + c³ - 3abc = 0.

Calculations:

According to question,

⇒ (r - s) + (s - t) + (t - r) = 0

So, $\frac{{{{\left( {{\rm{r - s}}} \right)}^{\rm{3}}}{\rm{ + }}{{\left( {{\rm{s - t}}} \right)}^{\rm{3}}}{\rm{ + }}{{\left( {{\rm{t - r}}} \right)}^{\rm{3}}}}}{{{\rm{6}}\left( {{\rm{r - s}}} \right)\left( {{\rm{s - t}}} \right)\left( {{\rm{t - r}}} \right)}}$

⇒ $\frac{3(r-s)(s-t)(t-r)}{6(r-s)(s-t)(t-r)}$ = $\frac{1}{2}$

∴ The value of $\frac{{{{\left( {{\rm{r - s}}} \right)}^{\rm{3}}}{\rm{ + }}{{\left( {{\rm{s - t}}} \right)}^{\rm{3}}}{\rm{ + }}{{\left( {{\rm{t - r}}} \right)}^{\rm{3}}}}}{{{\rm{6}}\left( {{\rm{r - s}}} \right)\left( {{\rm{s - t}}} \right)\left( {{\rm{t - r}}} \right)}}$is $\frac{1}{2}$.

Given:

Cheating percent while buying and selling = 6%

Formula Used:

Profit % = [(S.P - C.P)/C.P × 100]

Calculation:

Shopkeeper buy 106 gm goods instead of 100 gm by cheating

And he sells 94 gm instead of 100 gm

According to the question

SP/CP = (106 × 100)/(100 × 94) = $\frac{53}{47}$

Profit = SP - CP

Profit = 53 - 47 = 6

Profit Percentage = ($\frac{6}{47}$) × 100% = 12.77%

∴ The shopkeeper earned 12.77% profit.

Radius of roller = 14 cm

Length = 20 cm

Concept used:

Curved surface area of cylinder = 2πrh

Calculations:

According to question,

Curved surface area of roller = 2πrh

⇒ 2 × ($\frac{22}{7}$) × (14) × (20) = 1760 cm².

Given:

α is an acute angle.

Calculations:

Let us check the options one by one till we found the right one:

Option 1 : $\frac{1}{cosα}$ = secα, hence it is not equal to cosecα.

Since it is the option we wanted to figure out so we don't need to check other options.

∴ cosecα is not equal to $\frac{1}{cosα}$.

Mistake Points

α = 45° is a specific case in which

1/cos α = cosec α

But for every value of α, it is not true.

Given:

Radius of base of Cylinder = diameter/2 = 28/2 = 14 cm

Height of cylinder = 70 cm

Concept used:

Total surface area of cylinder = 2πrh + 2πr²

Calculations:

According to question,

Total surface area of the cylinder is

⇒ 2πrh + 2πr²

⇒ 2 × ($\frac{22}{7}$) × (14) × (70) + 2 × ($\frac{22}{7}$) × (14)²

⇒ 6160 + 1232

⇒ 7392

$\therefore$ Total surface area of Cylinder is 7392 cm².
