Logic:  Second Number = (First Number /3) x 5

In **72 : 120 **→

(72/3) x 5 = 24 x 5 = 120

In 84 : 140 →

(84/3) x 5 = 28 x 5 = 140

Similarly:

In 153 :   →

(153/3) = 51x 5 = 255

Here, 153 : 255 is the correct pair as per the logic.

Hence, the correct answer is "255".

We have drawn the figure according to the information given in the question,

(Let the turning points as shown in the figure)

Sunita started from A and her journey ends at B.

Initial Northward Journey AC = BD = 4 km

Hence, 4 km is the correct answer.

Hence, the correct answer is "SYHIORT".

The logic followed here is:

'Nest' is created from "Straw".

Similarly,

'Thread' is created from "Cotton".

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

The distance and direction diagram is according to the given data:

Here, O is the starting point and D is the endpoint and the distance between O and D is 12 km.

The direction of D from O is West.

Here, the distance and the direction of D from O is 12 km in the west.

Hence, Option(2) is the answer.

Table shows the positional value of letters.

The logic followed here is: 

Letters are coded as their reverse or opposite letters.

'PRIYANKA' is codded as ‘KIRBZMPZ'.

'FUNCTION' is codded as 'UFMXGRLM'.

Hence, the correct answer is "option (3)".

Additional Information

Decoding the information, 

Given:

A ÷ 2 - ? + B = 1

Let the “?” is replace with “Z”

After replacing the signs from left to right and using the BODMAS rule,

=> 6 × 2 - Z + 3 = 1

=> 12 – Z + 3 = 1

=> 15 - Z = 1

=> Z = 15 – 1

=> Z = 14

Hence, “14” is the correct answer.

The shaded part represents the number of singers who are director but not actor.

The shaded part represent the number of actor who are singer but not director.

Difference between the number of singer who are director but not actor and the actor who are singer but not director = 7 - 3 = 4

Hence, the correct answer is "option (4)".

According to the statement:

Blue color balls who are not red = 12 + 4 = 16

Yellow color balls who are not red and blue = 9

Ratio of blue color balls who are not red and yellow color balls who are not red and blue = 16 : 9 

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

Statement I : 42 S 21 P 64 Q 6 R 2 = 50

After applying the codded symbols

42 ÷ 21 + 64 - 6 × 2 = 50

⇒ 42 ÷ 21 + 64 - 6 × 2 = 50

⇒ 2 + 64 - 6 × 2 = 50

⇒ 2 + 64 - 12 = 50

⇒ 66 - 12 = 50

⇒ 54 ≠ 50

Statement II: 42 P 4 R 2 Q 3 S 1 = 47

After applying the codded symbols

42 + 4 × 2 - 3 ÷ 1 = 47

⇒ 42 + 4 × 2 - 3 ÷ 1 = 47

⇒ 42 + 4 × 2 - 3 = 47

⇒ 42 + 8 - 3 = 47

⇒ 50 - 3 = 47

⇒ 47 = 47

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

The logic follows here is :-

Figure 1 to figure 2 → The fourth line is rotated 180⁰ and moves one step upward the same repeats for third and second line, and first line is removed and new fourth line added.

Figure 2 to figure 3 → The fourth line is rotated 1800 and moves one step upward the same repeats for third and second line, and first line is removed and new fourth line added.

This process repeats until figure 6 as shown below.

Thus, the correct answer is "Option 2".

Given: 

The logic followed here is: 

1. The last symbol comes in the front, in each figure. Every other element moves one step towards the right.
2. All the other symbols (except the one that comes in front) are rotated 180° in each step.

Therefore, in the answer figure, the arrow with a triangular head should come in front and all the other symbols should be rotated 180°.

Thus, the final series is as follows,

Hence, option (3) is the correct answer.

Hint

If exact figure is not shown in options, mark the most appropriate option present.

On observing the given figures carefully, we get:

In the question figure (X),

1. One dot is in the common area of the rectangle and triangle.
2. One dot is in the common area of the triangle and circle.
3. One dot is in the common area of the square and triangle.

Figure (A) → All the required conditions are fulfilled as shown below:

Figure (B) → Common area of only triangle and square isn't present.

Figure (C) → Common area of the circle and triangle isn't present.

Figure (D) → Common area of the rectangle and triangle isn't present.

Hence, the correct answer is "Figure (A)".

We should not think of the exact shape and size of the figures in these questions.

Just resemblance will work like if an Equilateral triangle is given in the question figure, any shape of a triangle in the answer figure will work, be it right triangle or scalene triangle.

In the question figure, one of the dots lies in the common region of triangle and diamond only, and the second dot lies in the region common to arrow, rectangle, and triangle. Only figure (A) consists of these types of regions.

In figure (B), rectangle and arrow do not share any common area.

In figure (C), triangle and arrow do not share any common area.

In figure (D), triangle and diamond do not share any common area.

Hence, only figure (A) has all the types of figures required.

Hence, “A” is the correct answer.

In question figure, one of the dots lies in the region common to circle and rectangle only, and the second dot lies in the region common to all the figures. Only figure (C) consists of these types of regions.

In the figure (A) and (B), hexagon and rectangle are not sharing any common region.

In figure (D), hexagon and rectangle are not sharing any common region with heart.

Hence, only figure (C) has all the types of figures required.

Hence, “C” is the correct answer.

Given: 

The logic followed here is: sum of the positional values, as shown below:

D + G → 4 + 7 = 11,

P + L → 16 + 12 = 28

J +  M → 10 + 13 = 23

Similarly, 

? + H → ? + 8 = 32

? = 32 - 8

? = 24

We know that 24 is the positional value of X.

⇒ ? = X

Hence, X is the correct answer.

By using the symbol in the table given below, we can draw the following family tree.

 As a maternal uncle of Brijesh is Alka's brother and Alka's father is also the father of Brijesh's maternal uncle. Here Alka is the mother of Brijesh.

Hence the correct answer is Mother.

Preparing the family tree using the following symbols,

Given:

1. Garima is the wife of Kanika's brother.

2. Kanika is the daughter of Kishore, who is the husband of Sujata.

3. Piyush is the son of Sujata's only son Aman.

• Sujata's only son means Garima is the wife of Aman.

Hence, Aman is the "Son" of Kishore.

The logic follows here is:

1) 

⇒ 3² + 2² 

⇒ 9 + 4 

⇒ 13

2) 

⇒ 9² + 1²

⇒ 81 + 1

⇒ 82

Similarly,

3) 

⇒ 6² + 3²

⇒ 36 + 9

⇒ 45

Hence, the correct answer is 45.

Hence, the figure given in option 2) will complete the pattern.

The least possible Venn diagram for the given relation is a shown below :

Machinery and Product are the parts of Factory.

Hence, the correct answer is "Option (4)".

Given:

X can complete work at the same time in Y and Z together

X and Y together can finish it in 10 days and

Z alone in 15 days

Calculation:

Let one day's work of X, Y, and Z be 1/x,1/y & 1/z  

According to the question, Z alone can finish the work in 15 days

1/z = 1/15             -----(1)

The efficiency of X =  Efficiency of (Y + Z)

1/x  = 1/y + 1/z    

⇒ 1/x = 1/y + 1/15         [From equation (1)]

⇒ 1/x - 1/y = 1/15    -----(2)

X and Y together can finish it in 10 days

1/x + 1/y = 1/10     -----(3)

Doing equation (3) - (2)

⇒ 2/y = 1/10 – 1/15

⇒ 2/y = (3 - 2)/30 = 1/30

⇒ y = 60 days

∴ Y alone can complete it in 60 days.

Shortcut Trick

Original Ratio = 7 : 8

Increase: Boys = 20%, Girls = 10%

New Ratio = (7 × 120) : (8 × 110)

New Ratio = 84 : 88

Simplified New Ratio = 21 : 22

∴ The correct option is B.

Alternate Method

Given: Ratio of boys to girls = 7 : 8. Increase in boys = 20%, Increase in girls = 10%.

Boys (7 units) +20%

Girls (8 units) +10%

New Ratio = 7(120%) : 8(110%) = 84 : 88 = 21 : 22

Let the original number of boys = 700x and girls = 800x.

⇒ Number of boys after 20% increase = 700x + 20% of 700x

⇒ New Boys = 700x + (20/100) × 700x = 700x + 140x = 840x

⇒ Number of girls after 10% increase = 800x + 10% of 800x

⇒ New Girls = 800x + (10/100) × 800x = 800x + 80x = 880x

⇒ New Ratio = New Boys : New Girls = 840x : 880x

⇒ New Ratio = 84 : 88

⇒ New Ratio = 21 : 22

∴ The correct option is B.

Additional Information

Percentage Increase Formula

To increase a value by x%, multiply the original value by (100 + x)/100.

Ratio Multiplier Method

When components of a ratio a : b are changed by factors m and n, the new ratio becomes (a × m) : (b × n).

Simplification of Ratio

A ratio remains unchanged if both terms are multiplied or divided by the same non-zero number.

Given:

Percentage of alcohol in a whisky jar = 40%

Percentage of alcohol in another whisky jar = 19%

Percentage of alcohol after mixing the contents of two jars = 26%

Calculation:

By Alligation Method

∴ Ratio of the contents of jar-1 and jar-2 = 1 : 2 

⇒ The quantity of whisky replaced was 2/3 of the whole mixture.

Alternate MethodConcept: Use the concept of mixture and alligation.

Calculation:

Difference in concentration between initial whisky and final mixture  = 40 - 26 = 14

Difference in concentration between replacement whisky and final mixture = 26 - 19 = 7

Ratio of the parts replaced to the remaining part:

Ratio = Difference with replacement whisky / Difference with original whisky

⇒ 14 / 7 = 2 / 1

The quantity of whisky replaced is 2 parts out of (2 + 1) = 3 parts in total.

 ∴  2/3 of the jar was replaced.

Concept:

Divisblity rule of 9: if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9

Calculation:

We have 481A673

If the number is divisible by 9 then

4 + 8 + 1  + 6 + 7 + 3 = multiple of 9

⇒ 29 + A = multiple of 9

If A = 7, sum become 36 which is divisible by 9.

∴ Smallest whole number is 7.

Calculation:

Total women = 1/3

Married women = 1/2 of 1/3 = 1/6

Women who have a child = 1/3 of married women

⇒ Women who has child = 1/3 of 1/6 = 1/18

Total men = 2/3       (∵ 1/3 are women)

Married man = 3/4 of the total man

⇒ Married man = 3/4 of 2/3 = 1/2

Man who has a child = 2/3 of a married man

⇒ Men who has child = 2/3 of 1/2 = 1/3

Men + Women (​​​​having child) = 1/18 + 1/3 = 7/18

Part that don't have child = 1 - 7/18 = 11/18

∴ 11/18 workers don't have children.

Given :

S.I on money for 2 year at 5% = Rs. 50

Formula used :

S.I. = P × R × T / 100 

Amount (A) = P(1 + R/100)ⁿ

C.I = A - P

Where,

P = principal, R= Rate, T= Time

Calculation : 

We know that

S.I. = P × R × T / 100 

50 = P × 5 × 2 /100 

⇒ P = 500

Again, in compound interest, the amount

⇒ A = 500(1 + 5/100)² 

⇒ A = 500 (1 + .05)²

⇒ A = Rs. 551.25 

Hence, compound interest

C.I = 551.25 - 500 = Rs. 51.25

∴ Compound Interest = Rs. 51.25

Shortcut Trick

Combined work of Ravi and Raghav for 10 days (25 − 15) is done by Raghav alone in 20 days.

Efficiency Ratio (Ravi + Raghav) : Raghav = 20 : 10 = 2 : 1.

Total Work = Combined Efficiency × Total Days = 2 × 25 = 50 units.

Time taken by Raghav alone = Total Work ÷ Raghav efficiency = 50 ÷ 1 = 50 days.

∴ The correct answer is 50 days.

Alternate Method

Given:

Time taken by (Ravi + Raghav) = 25 days.

Work done together = 15 days.

Remaining work done by Raghav = 20 days.

Formula Used:

Work = Efficiency × Time

Calculations:

⇒ Let the efficiency of Ravi be 'a' and Raghav be 'b'.

⇒ Total Work = 25 × (a + b)

⇒ Work done in 15 days = 15 × (a + b)

⇒ Remaining Work = 25(a + b) − 15(a + b) = 10(a + b)

⇒ According to the question, 10(a + b) = 20 × b

⇒ 10a + 10b = 20b

⇒ 10a = 10b ⇒ a = b (Efficiencies are equal)

⇒ Total Work = 25 × (b + b) = 50b

⇒ Time taken by Raghav alone = 50b ÷ b = 50 days.

∴ The correct answer is 50 days.

Additional Information

Efficiency and Time Relationship

Efficiency is inversely proportional to the time taken to complete a work. If the ratio of efficiencies of A and B is x : y, then the ratio of time taken is y : x.

Work and Wages

Wages are always distributed in the ratio of the actual work done by each individual, which is equivalent to the ratio of their efficiencies if they work for the same duration.

Combined Work Formula

If A takes 'x' days and B takes 'y' days, together they take (x × y) ÷ (x + y) days to complete the work.

Given:

234.01 × k/12.99 − 29.9% of 499.9 = 810.01 ÷ 26.98

Concept used:

To find the approximate value of the expression we can round off the decimal values to the nearest integers to make our calculation easier.

Follow the BODMAS rule according to the table given below:

Calculation:

234.01 × k/12.99 − 29.9% of 499.9 = 810.01 ÷ 26.98

⇒ 234 × k/13 - 30% of 500 = 810 ÷ 27

⇒ 234 × k/13 - 30 × 5 = 810 ÷ 27

⇒ 18 × k - 150 = 30

⇒ k = 180/18 = 10

∴ The approximate value of k = 10.

Shortcut Trick

If the ratio of two numbers is a : b and they are co-prime, then:

H.C.F = L.C.M ÷ (a × b)

H.C.F = 147 ÷ (3 × 7)

H.C.F = 147 ÷ 21 = 7

∴ The correct answer is 7.

Alternate Method

Given:

Ratio of two numbers = 3 : 7

L.C.M of the two numbers = 147

Concept Used:

If two numbers are in the ratio a : b, their L.C.M = a × b × H.C.F.

Calculations:

⇒ Let the numbers be 3x and 7x, where x is the common factor (H.C.F).

⇒ L.C.M of 3x and 7x = 3 × 7 × x = 21x

⇒ Given L.C.M = 147

⇒ 21x = 147

⇒ x = 147 ÷ 21

⇒ x = 7

⇒ Therefore, the H.C.F of the two numbers is 7.

∴ The correct answer is 7.

Additional Information

Product Rule

For any two numbers, the product of the numbers is always equal to the product of their H.C.F and L.C.M (Product = H.C.F × L.C.M).

Co-prime Numbers

Two numbers are considered co-prime if their H.C.F is 1. The terms of a simplified fraction or ratio are always mutually co-prime.

H.C.F and L.C.M Divisibility

The H.C.F of two or more numbers is always an exact divisor of their corresponding L.C.M.

Shortcut Trick5% of C.P - 4% of C.P = 6

⇒ 1 % of C.P = 6

⇒ 100 % of CP = 600

∴ Cost of T-shirt is 600 Rs.

Alternate Method

Formula used:

S.P. = C.P (1 + P%/100)

Calculation:

Using the above formula,

SP₁ = CP(1 + 4/100)

⇒ SP₁ = (26/25)C.P      -----(1)

SP₂ = (1 + 5/100)

⇒  SP₂ = (21/20)C.P      -----(2)

According to the question, 

SP₂ - SP₁ = 6

⇒ (21/20 - 26/25)C.P = 6

⇒ (105 - 104)C.P / 100 = 6

⇒ CP = 600 Rs.

∴ Cost of T-shirt is 600 Rs.

Formula used:

S.P = C.P (1 + P%/100)

Calculation:

Let cost of each pen be ₹ x

Cost of 90 pen = ₹90 x

SP of 40 pens at 10% gain = 40x + 4x = 44x

SP of 50 pens at 20% gain = 50x + 10x = 60x

Total SP = 44x + 60 x = 104x

If uniform profit of 15% was made, then 

SP = 90x + 15% of 90 x

SP = 90 x + 13.5 x = 103.5 x

According to problem,

104 x - 103.5 x = 40

⇒ 0.5 x = 40

⇒ x = 80

∴ CP of each pen is Rs 80.

Given:

Length of cloth = 37.5 meters 

1 meter  = 8 pieces

Calculation:

1 meter = 8 pieces 

Then, pieces in 37.5 meters cloth  = 37.5 × 8 = 300

∴ 300 pieces will be made in the whole cloth

Formula Used:

The angle between the hour hand and minutes hand

θ = (30H - 11 M/2)

Calculation:

H = 7 and angle = 0°

When minute & hour hands coincide, then θ = 0

⇒ 0 = 30 × 7 - 11 M/2

⇒ 0 = 210 - 11 M/2

⇒ 210 = 11 M/2

⇒ 420 = 11 M

⇒ M = $\frac{420}{11}$

⇒ M = $38\frac{2}{11}$ Minutes

∴  The correct answer is $38\frac{2}{11}$ minutes past 7.

Given:

Lenght = 125 m, breadth = 65 m

Cost of flooring = 10 rs/m²

Formula used:

Area of rectangle = Length × Breadth

Calculation:

Area of park = Length × Breadth

⇒ Area of park = 125 m × 65 m

⇒ Area of park = 8125 m²

Length of rectangle including path = 125 + 3 + 3 = 131 m

Breadth of rectangle including path = 65 + 3 + 3 = 71 m

Area of the park including the path

= 131 m × 71 m = 9301 m²

Area of the path = Area of the park including path - Area of the park

⇒ A = 9301 m² - 8125 m²

⇒ A = 1176 m²

Hence, total cost of flooring @ 10 Rs/m²

⇒ 1176 × 10 = 11760 Rs.

∴ Total cost of flooring the path is 11760 Rs.

Shortcut Trick

Sum of ratio units = 7 + 5 + 3 + 4 = 19 units.

Total value → 19 units = ₹76.

Value of 1 unit = 76 ÷ 19 = ₹4.

Smallest part ratio = 3 units.

Smallest part value = 3 × ₹4 = ₹12.

∴ The correct answer is ₹12.

Alternate Method

Given: Total Amount = ₹76, Ratio = 7 : 5 : 3 : 4

Formula: Value of a part = (Ratio of part ÷ Sum of ratios) × Total Amount

Ratio 7 Ratio 5 Ratio 3 Ratio 4 (Smallest)

Total = ₹76 (Sum of 19 units)

⇒ Sum of ratio parts = 7 + 5 + 3 + 4 = 19

⇒ Smallest part corresponds to the ratio 3.

⇒ Smallest part = (3 ÷ 19) × 76

⇒ Smallest part = 3 × 4

⇒ Smallest part = ₹12

∴ The correct answer is ₹12.

Additional Information

Ratio and Proportion

A ratio compares two or more quantities. When dividing a total value X into parts with ratio a : b : c, the parts are [a/(a+b+c)]×X, [b/(a+b+c)]×X, and [c/(a+b+c)]×X respectively.

Compounded Ratio

For two ratios a : b and c : d, the compounded ratio is (a × c) : (b × d).

Duplicate and Sub-duplicate Ratio

The duplicate ratio of a : b is a² : b², while the sub-duplicate ratio is √a : √b.

Given:

The diameter of the driving wheel = 140 cm

Speed of a bus = 66 km/hr

Concept used:

Circumference of a circle = 2πr

Number of revolutions of a wheel (N) = D/d

Where, D = Total distance traveled by wheel

d = Distance traveled by the wheel in 1 revolution

Calculation:

Distance travelled by bus in 1 hour = 66 km = 66000 meter

Distance traveled by bus in 1 minute = (66000)/60 = 1100 m

Distance traveled by a wheel in 1 revolution = Circumference  = 2πr

Put 2r = 140 cm & 1 m = 100 cm, π=22/7 

Therefore, 

Distance traveled by a wheel in 1 revolution = (22/7) × (140/100) 

Distance traveled by a wheel in 1 revolution = 4.40 m

Now, using the above formula

⇒ N × 4.4 = 1100

⇒ N = 250 

∴ The number of revolutions per minute is 250.

Calculation:

Let the required number be N.

According to the question, 

$\frac{N}{5}+4 = \frac{N}{4}-10$

⇒ $\frac{N}{4} - \frac{N}{5} = 14$

⇒ $\frac{5N-4N}{20} = 14$ 

⇒ N = 280

∴ The required number is 280

Formula used:

Average Speed = 2ab/(a + b)

• Applicable when one travels at speed a for half the distance and speed b for the other half of the distance.
• In this case, the average speed is the harmonic mean of the two speeds. On similar lines, you can modify this formula for one-third distance.

Calculation:

As Amit cover the same distance in both ways, hence 

Using the above concept

Average speed = $\frac{2 \times 75 \times 45}{75+45}$

∴ Average speed = 56.25 km/hr 

Additional Information

1. Average Speed = (a + b)/2

• Applicable when one travels at speed a for half the time and speed b for another half of the time.
• In this case, the average speed is the arithmetic mean of the two speeds.

2. Average Speed = 3abc/(ab + bc + ca)

• Applicable when one travels at speed a for one-third of the distance, at speed b for another one-third of the distance and speed c for rest of the one-third of the distance.

Concept:

The probability of any event to occur = $\rm \text{The required number of cases}\over\text{Total number of cases possible}$

Calculation:

The total number of cases possible are = 6 × 6 = 36

The sum of the numbers that appear in the 2 dice are ∈ [2, 12]

The prime numbers in that interval are 2, 3, 5, 7, 11

2 ⇒ (1, 1)

3 ⇒ (2, 1) and (1, 2)

5 ⇒ (1, 4), (4, 1), (2, 3) and (3, 2)

7 ⇒ (1, 6), (6, 1), (2, 5), (5, 2), (3, 4) and (4, 3)

11 ⇒ (5, 6) and (6, 5)

Total cases required = 15

∴ The probability of the required cases (P) = $15\over36$ 

P = $\boldsymbol{5\over12}$

Concept:

Relative Speed:

If two objects are moving with speeds X  and Y, then,

1. Moving in the opposite direction:

Relative speed = X + Y

2. Moving in the same direction: 

Relative speed = X - Y

Formula used: 

Distance = Speed × Time

Calculation:

Let x km/hr be the speed of the train.

Relative speed = (x + 5) × (5/18) m/sec

As per the question,

⇒ $\frac{{100}}{{\left( {x + 5} \right) \times \frac{5}{{18}}}} = \frac{{36}}{5}$

⇒ $1800 = \frac{{36}}{5}\left( {5x + 25} \right)$

⇒ 5x = 225

⇒ x = 45 km/hr

∴  Speed of the train is 45 km/hr
