Answers:

Directions (Q. 1 – 5):

1. Answer c

 (28/9)*(17/8)*(6/153) + (95/54) = x

X = (7/27) + (95/54)

X = (14 + 95)/54 = 109/54 = 2 1/54

2. Answer a

 (28/100)*3540 + (267/100)*4500 + (24/100)*5060 = x

X = 991.20 + 12015 + 1214.4

X = 14220.6

3. Answer d

 [(25/3) * (27/175)] ÷ (33/14 – 29/28) = x

X = (9/7) ÷ (37/28)

X = (9/7)*(28/37) = 36/37

4. Answer b

 (21/5)*2755 + 281 + (36/5)*8000 = x

X = 11571 + 281 + 57600

X = 69452

5. Answer a

 (7868/14)*37 + 175 + 1089 = x

X = 20794 + 175 + 1089

X = 22058

Directions (Q. 6 – 10):

6. Answer e

The pattern is, *0.5 -0.5, *1 + 1, *1.5 – 1.5, *2 +2, *2.5 -2.5,..

The answer is, 41 

7. Answer d

The pattern is, +53, +62, +73, +82, +93,..

The answer is, 1568

8. Answer a

The pattern is, ÷ 11, *7, ÷ 5, *3, ÷ 2…(Prime no’s)

The answer is, 214.2

9. Answer c

The difference of difference of difference is, 3, 3, 3,..

The answer is, 783

10. Answer b

The pattern is, ÷ 2 +1, ÷ 3 +3, ÷ 4 +5, ÷ 5 +7,..

The answer is, 12.4

11. Answer d

Present age of Vinay = Ragu’s age, 8 years ago

6 years hence, Vinay: Ragu = 3:4 (3x, 4x)

Present ages will be, 3x-6, 4x-6

According to the question,

3x-6 = 4x-6-8

X=8

Present age of Vinay = 3x-6 = 24-6 =18 years

12. Answer a

According to the question,

(16/24) + (x/27) =1

(2/3) + (x/27) =1

(x/27) =1 – (2/3)

(x/27) =1/3

X= 9 days 

13. Answer c

Rajeev’s score = 532 marks, Seema’s score = 56 % = Rajeev’s score – 28

Seema’s score = 532 – 28 = 504 = 56% of total marks

(56/100)*x = 504

X = 504*(100/56) = 900

Minimum passing marks = 35 % of total marks

= > (35/100)*900 = 315

Rajeev scores 217 marks more than the passing marks.

14. Answer b

Sum of the present age of two persons = 42*2 = 84

12 years back, the ratio between their ages = 1: 3(x, 3x)

X + 3x + 24 = 84

4x = 60

X = 15

Present age of two persons = x + 12, 3x + 12 = 27 and 57

Required difference = 57 – 27 = 30 years

15. Answer a

The share of A, B and C

= > [24000*4 + 24000*(1/3)*8]: [32000*4 + 35000*8]: [35000*5]

= > 160000: 408000: 175000

= > 160: 408: 175

743’s = 92132

1’s = 124

The share of B = Rs. 50592

Directions (Q. 16 – 20)

16. Answer b

Total number of Basic model cars produced by Company T of all the given years together

= > [5.1 + 5.7 + 5.7 + 4.9 + 5.3] thousand

= > 26700

Required % = [(26700 – 25800)/26700]*100 = 3.37 % = 3 % less

17. Answer d

Total number of premium model cars produced in the year 2014 of all the given companies together

= > [1.4 + 1.6 + 1.5 + 1.7 + 1.3] thousand

= > 7500

Required % = (8100/7500)*100 = 108 %

18. Answer c

The total number of basic cars produced by company Q, R and T in the year 2013, 2015 and 2017 together

= > [5.7 + 5.9 + 5.8 + 5.2 + 6.4 + 5.5 + 5.1 + 5.7 + 5.3] thousand

= > 50600

The total number of basic cars produced by company P, S and T in the year 2014, 2016 and 2017 together

= > [4.7 + 4.9 + 5.3 + 5.5 + 4.3 + 5.4 + 5.7 + 4.9 + 5.3] thousand

= > 46000

Required ratio = 50600: 46000 = 253: 230

19. Answer a

Total number of cars (Basic + Premium) produced by company R of all the given years together

= > [5.2 + 2.4 + 5.4 + 1.8 + 6.4 + 1.1 + 4.2 + 2.2 + 5.5 + 1.5] thousands

= > 35700

Required average = 35700/5 = 7140

20. Answer c

The total number of cars (Basic + Premium) produced by company S of all the given years together

= > [6.3 + 5.5 + 6.1 + 4.3 + 5.4 + 2.5 + 1.6 + 1.9 + 1.4 + 1.7] thousand

= > 36700

The total number of cars (Basic + Premium) produced by company Q of all the given years together

= > [5.7 + 4.2 + 5.9 + 4.5 + 5.8 + 1.3 + 1.4 + 1.7 + 1.5 + 1.6] thousand

= > 33600

Required difference = 36700 – 33600 = 3100
