Answers:

Directions (Q. 6-10):

6). Answer c

[( √530 x 36.003) ÷ 47.987] x ? = 5863.10376

? = 5863 / [( √529 x 36) ÷ 48] = 5863 / [(23 × 36) ÷ 48] = 340

7). Answer a

? = (77.987% of 358) + (68.55% of 729)

? = [(78/100) × 358] + [(69/100) × 725]

= 280 + 500 = 780

8). Answer d

√624.995 + (4.9989)^2

= ? ÷ (1 / 4.9900865)

or, √625 + (5)2= ? ÷ (1/5)

? = 1/5 (25 + 25) = 10

9). Answer b

? = 989.001 + 1.00982 × 76.792

= 990 + 1 x 76 = 1066

10). Answer e

(?)2= 63.9872 x 9449.8780 ÷ 243.0034

= 64 x 9450 ÷ 243 = 64 x 39 = 2496

Now, (?)2 = 2496

? = 50

  1. Correct Answer is: c

A alone completes the work in 8 days. So, he does 1/8th of the work in 1 day.

B alone completes the work in 12 days. So, he does 1/12th of the work on 1 day.

Hence, total work completed together in 1 day

= (1/8) + (1/12) = 5/24

A and B work together for only 3 days.

Work completed together in 3 days = 3*(5/24) = 15/24

Amount of work that B has to complete alone = 1 – (15/24) = 9/24

Number of days that B will take to complete the work = (9/24) / (1/12) = 4.5 days

Hence, B can finish the remaining work in 4.5 days.

  1. Correct Answer is: c

Total profit = (832/13)*23*(100/92)=1600

  1. Correct Answer is: b

We know that, A = P (1+R/100)T

27,783 = 24,000 (1+5/100)T

(21/20)T=9261/8000

(21/20)T=(21/20)3

T = 3 years

Hence the required time = 3 years

14.

  1. Correct Answer is: b

=> Percentage of employees who choose HRA = 72%

=> Percentage of employees who choose Old Pension Scheme = 44%

=> Percentage of employees who selected both = 72+44-100

=16%

=> Which is equal to 40 (given)

=> Therefore, total employees = 40*100/16

=250

Directions (Q. 16-20):

  1. Correct Answer is: e)

Total marks scored by Sankar in all the subjects together

= 75 × 0.56 + 75 × 0.66 + 200 × 0.55 + 50 × 0.76 + 150 × 0.66

= 42 + 49.5 + 110 + 38 + 99

= 338.5

  1. Correct Answer is: c)

Total marks obtained by Milan

= (75 ×0.82) + (150 × 0.70)

= 61.5 + 105

= 166.5

Total marks obtained by Sankar

= (75 × 0.66) + (150 + 0.66)

= 49.5 + 99

= 148.5

Difference = 166.5 – 148.5 = 18

  1. Correct Answer is: d)

Marks scored by Ranjith in Reasoning

= 75 × 0.72 = 54

Marks scored by Ranjith in English

= 150 × 0.64 = 96

Required % = 54/96 × 100

= 56.25%

= 56%

  1. Correct Answer is: a)

Average marks of all students in Reasoning

= 1/6 [75 × (0.84 + 0.68 + 0.72 + 0.48 + 0.70 + 0.56)]

= 1/6 [75 × 3.98]

Average = 298.5/6

= 49.75

  1. Correct Answer is: b)

Marks scored by Suresh

= 75 × 0.68 + 75 × 0.64 + 200 × 0.49 + 50 × 0.74 + 150 × 0.52

= 51 +48 + 98 + 37 + 78=312

Required % = 312/550 × 100

= 56.72%

= 57%
