Answers:

Directions (Q. 1-5):

1). Answer: d

(4809.01 + 9615.96 + 14425.03) ÷ 4.98 + 6.02 = (?)²

Or, (?)^2 = [(4809 + 9616 + 14425) / 5] +6

= (28850/5) + 6 = 5770 + 6

Or, ?^2 = 5776

? = √5776 = 76

2). Answer: b

(35% of 74000) ÷ ? = (123% of 13.02)^2 x 2.01

Or, (35×74000)/100 ÷ ? =  [(123×13) / 100]^2x 2

or, 25900 / ? = (15.99)² × 2

or, (25900/?) = 16×16×2

?= 25900 / (16×16×2) = 50.58 = 50

3). Answer: a

4/15 of 393 + 7/12 of 473 = ? x (1.99 + 1.01)

or, ? x 3 = (4/15) x 393 + (7/12) x 473

or, ? x 3 = 105 + 273

or, ? = 378/3 = 126

4). Answer: c

18% of 256 + 35% of 290 – 15% of 385=?

Or, ? = (18/100) × 256 + (35/100) × 290 – (15/100) × 385

= 46 + 102 – 58 = 148 – 58 = 90

5). Answer: a

8  4/7 + 9  3/4 – 3  5/8 – ? = 6  29/56

Or, ? = (8+9-3-6) + (4/7 + 3/4 – 5/8 – 29/56)

= 8 + [(32 + 42 – 35 – 29) / 56] = 8 + 10/56 = 8

Directions (6-10):

6. Answer d

32 + 17 = 49

49 + 34 = 83

83 + 68 = 151

151 + 136 = 287

287 + 272 = 559

559 + 544 = 1103

7. Answer a

1050 × 0.4 = 420

420 × 0.4 = 168

168 × 0.4 = 67.2

67.2 × 0.4 = 26.88

26.88 × 0.4 = 10.752

10.752×0.4 = 4.3008

8. Answer d

15 + 3 = 18

18 – 2 = 16

16 + 3 = 19

19 – 2 = 17

17 + 3 = 20

20 – 2 = 18

9. Answer b

462 + 90 = 552

552 + 98 = 650

650 + 106 = 756

756 + 114 = 870

870 + 122 = 992

992 + 130 = 1122

10. Answer d

0   6   24   60   120   210

+6 +18 +36 +60 +90

Look at the differences of two consecutive terms of the series. We get the following pattern:

0 + 6 × 1 = 6

6 + 6 × 2 = 18

18 + 6 × 3 = 36

36 + 6 × 4 = 60

60 + 6 × 5 = 90

90 + 6 × 6 = 126

Hence, the required term = 210 + 126 = 336

Directions (Q. 11-15):

11. Answer e

Passed students from IBPS Exam= 37500

Passed students from RRB Exam = 17500

Difference = 37500 – 17500

= 20000

12. Answer d

Passed Boys from IBPS Exam and SBI Exam

= 15000 + 17500

Passed Girls from RBI Exam and SSC Exam

= 35000 + 30000

% = 32500/65000 × 100 = 50%

13. Answer b

Passed Girls from RBI Exam = 35000

Passed Girls from All exams = 115000

Approximate % = 35000 / 115000 × 100 = 29.78% = 30%

14. Answer c

Average number of passed students in all Exams

Boys + Girls = Students

IBPS =15000 + 22500= 37500

SBI = 17500 + 20000= 37500

RBI = 27500 + 35000= 62500

SSC = 25000 + 30000= 55000

RRB = 10000 + 7500 = 17500

Total = 210000

Average = 210000/5

= 42000

15. Answer a

Ratio between passed all boys and all girls in all exams

= Boys : Girls

= 92500 : 117500

= 37 : 47

16. Answer b

Let the income of A and B be Rs 9n and 4n respectively and the expenditure of A and B be Rs 7m and 3m respectively.

Hence according to the question; 9n – 7m = 4000… (1)

Similarly; 4n – 3m = 2500… (2)

Solving (1) and (2) we will get; n = 5500, m = 6500

Hence income of A = 9n = Rs 49500, Income of B = 4n = Rs 22000

17. Answer c

Let’s assume interest rate = R%

Total interest paid by Vinod = Rs (6000 + 8000 – 10000)

= Rs 4000

Now total interest paid = Interest on Rs 10000 for 4 years + Interest on Rs 4000 (10000 – 6000) for 2 years

=> 4000 = (10000 X 4 X R)/100+ (4000 X 2 X R)/100

=>4000 = 400R + 80R

=>480R = 4000

=> R = 4000/480=8 1/3%

18. Answer c

Let the man takes ‘x’ hours to complete the work.

Time taken by boy = ‘x+15’

Work done by man in 1 hour = 1/x

Work done by man in 6 hours = 6/x

Work done by boy in 1 hour = 1/(x + 15)

Work done by boy in 18 hours = 18/(x+15)

According to the question,

181(x+15) + 6/x = 3/5

Solving we get x = 30hrs

Remaining 2/5 work is done by the man in 2*30/5 = 12 hrs

Total time = 18 + 6 + 12 = 36 hours

19. Answer d

Suppose KJO remained in business for N months

=> Ratio of profit = 55 x 12: 66 x N = 2:1

=> 10:N = 2:1

=> N = 5

KJO remained in business for 5 months.

So KJO joined SRK after (12-5) = 7 months

20. Answer d

Let the present age of Mokshada be x.

Sameers present age = x – 5

Govinda’s present age = x + 5

As per given, the ratio of ages of Sameer and Govinda was 5:7 five years ago.

So, x – 10 : x = 5 : 7

On solving, we get x = 35

So, the present age of Mokshada is 35 years.
