ANSWER KEYS and SOLUTIONS:

1) – D)2) – A)3) – E)4) – B)5) – E)6) – E)
7) – D)8) – D)9) – C)10) – B)

Solution 1: D)

1 year hence from now, let the age of ‘J’ will be ‘9x’ years

So, present age of ‘J’ = (9x – 1) years

1 year hence from now, age of ‘K’ = 9x × (10/9) = ‘10x’ years

So, present age of ‘K’ = (10x – 1) years

1 year ago, age of ‘K’ = (10x – 2) years

So, 1 year ago, age of ‘M’ = (10x – 2) × (5/4) = (12.5x – 2.5) years

So, present age of ‘M’ = 12.5x – 2.5 + 1 = (12.5x – 1.5) years

Sum of present ages of ‘K’ and ‘M = (10x – 1) + (12.5x – 1.5) = {22.5x – 2.5} years

ATQ;

22.5x – 2.5 = 110

Or, 22.5x = 110 + 2.5 = 112.5

Or, x = 112.5 ÷ 22.5 = 5

So, present ages of ‘J’, ‘K’ and ‘M’ is 44 (9 × 5 – 1) years, 49 (10 × 5 – 1) years and 61 (12.5 × 5 – 1.5) years, respectively.

So, the youngest person is ‘J’.

Number of years before when ‘J’ was 19 years old = 44 – 19 = 25 years

So, ratio of ages of ‘K’ and ‘M’ 25 years ago = (49 – 25):(61 – 25) = 24:36 = 2:3

Hence, option d.

Solution 2: A)

Time taken by ‘A’ alone complete the work in full efficiency = 24 × 0.75 = 18 days

Let the total work = 54 units

Then, efficiency of ‘A’ alone = (54/18) = 3 units/day

Combined efficiency of ‘A’ and ‘B’ = (54/10.8) = 5 units/day

So, efficiency of ‘B’ alone = 5 – 3 = 2 units/day

According to the question,

3 × t + 2 × (t – 8) = 54

Or, 3t + 2t – 16 = 54

Or, 5t = 54 + 16 = 70

Or, t = (70/5) = 14

Hence, option a.

Solution 3: E)

Let present ages of ‘P’ and ‘Q’ be ‘a’ years and ‘b’ years, respectively.

Therefore, a – 13 = 2 × (b – 13)

Or, a – 13 = 2b – 26

Or, a = 2b – 13……………. (1)

For I:

{(a + 15)/(b + 15)} = 25/19

Or, 19 × (a + 15) = 25 × (b + 15)

Or, 19a + 285 = 25b + 375

19a – 25b = 90…………… (2)

Putting value of ‘a’ in equation (2)

19 × (2b – 13) – 25b = 90

Or, 38b – 247 – 25b = 90

Or, 13b = 337

Or, b ~ 25.92

Therefore, present age of ‘Q’ = 25.92 years

Hence, I is false.

For II:

{(a + 13)/(b + 13)} = 25/19

Or, 19 × (a + 13) = 25 × (b + 13)

Or, 19a + 247 = 25b + 325

Or, 19a – 25b = 78…………… (3)

Putting value of ‘a’ in equation (3)

19 × (2b – 13) – 25b = 78

Or, 38b – 247 – 25b = 78

Or, 13b = 325

Or, b = 25

Therefore, present age of ‘Q’ = 25 years

Therefore, II is true.

For III:

(a + 17)/(b + 17) = 25/19

Or, 19(a + 17) = 25(b + 17)

Or, 19a + 323 = 25b + 425

19a – 25b = 102………… (4)

Putting value of ‘a’ in equation (4)

19 × (2b – 13) – 25b = 102

Or, 38b – 247 – 25b = 102

Or, 13b = 349

Or, b ~ 26.84

Therefore, present age of ‘Q’ = 26.84 years

Hence, III is false.

Hence, option e.

Solution 4: B)

Total cost when the hotel is booked for 25 people = 25 × 300 = Rs. 7,500Total cost when the hotel is booked for 80 people = 80 × 162.5 = Rs. 13,000So, variable cost for extra 55 people i.e. (80 – 25) = 13,000 – 7500 = Rs. 5,500Therefore, variable cost per person is = 5500 ÷ 55 = Rs. 100ATQ;25 × 100 + fixed cost = 7,500Or, fixed cost = Rs. 5,000So, total costs when booking the hotel for 100 people = 100 × 100 + 5000 = Rs. 15,000Required average = (15000/100) = Rs. 150

Hence, option b.

Solution 5: E)

Let height of the lid is ‘h’ cm

According to the question,

2 × (22/7) × (21/2) × (21 + h) = 1584

Or, h = 3

So, the height of the lid = 3 cm

Hence, option e.

Solution 6: E)

Since ‘p’ and ‘q’ are both real and equal,

So, √(B2 – 4AC) = 0

So, √(B2 – 4 × 400) = 0

Or, B2 = 1600

So, B = ±40

Hence, option e.

Solution 7: D)

Since ‘p’ and ‘q’ are both real and equal.

So, √(B2 – 4AC) = 0

So, √(B2 – 4 × 400) = 0

Or, B2 = 1600

So, B = ±40

At B = 40, the given equation becomes, x2 – 45x + 500 = 0

So, x2 – 25x – 20x + 500 = 0

Or, x(x – 25) – 20(x – 25) = 0

Or, (x – 20)(x – 25) = 0

So, x = 20 or x = 25

And, at B = -40, the given equation becomes x2 – (-35x) + 500 = 0

So, x2 + 35x + 500 = 0

Since, √{352 – (4 × 500)} is irrational, the roots of this equation are not real.

So, required roots = 20 and 25.

Hence, option d.

Solution 8: D)

From I:

x2 – 3x = 28

Or, x2 – 3x – 28 = 0

Or, x2 – 7x + 4x – 28 = 0

Or, x(x – 7) + 4(x – 7) = 0

Or, (x – 7)(x + 4) = 0

So, x = 7 or x = -4

From II:

y2 + 104 = 21y

Or, y2 – 21y + 104 = 0

Or, y2 – 13y – 8y + 104 = 0

Or, y(y – 13) – 8(y – 13) = 0

Or, (y – 13)(y – 8) = 0

So, y = 13 or y = 8

From III:

z2 = 4z + 32

Or, z2 – 4z – 32 = 0

Or, z2 – 8z + 4z – 32 = 0

Or, z(z – 8) + 4(z – 8) = 0

Or, (z – 8)(z + 4) = 0

So, z = 8 or z = -4

Therefore, correct relation is I – c, II – a, III – b.

Hence, option d.

Solution 9: C)

For series I:

465 × 2 = 930

930 ÷ 3 = 310

310 × 4 = 1240

1240 ÷ 5 = 248

248 × 6 = 1488

Therefore, x = 248

For series II:

180 + (34 × 1) = 214

214 – (34 × 2) = 146

146 + (34 × 3) = 248

248 – (34 × 4) = 112

112 + (34 × 5) = 282

So, 214 is the missing number in series II.

Hence, option c.

Solution 10: B)

For series I:

20 + 12 × 1 = 32

32 + 12 × 2 = 56

56 + 12 × 3 = 92

92 + 12 × 4 = 140

140 + 12 × 5 = 200

So, P = 62

For series II:

14 × 1 = 14

14 × 1.5 = 21

21 × 2 = 42

42 × 2.5 = 105

105 × 3 = 315

315 × 3.5 = 1102.5

So, Q = 110

For series III:

124 – 17 = 107

107 – 17 = 90

90 – 17 = 73

73 – 17 = 56

56 – 17 = 39

So, R = 42

So, P < Q > R

Hence, option b.
