Answers:

1). Answer d

[518*2759] / [(23/100)*1000] = 35*(351/9) + x – 5300

[518*2760] / 230 = 1365 + x – 5300

6216 – 1365 + 5300 = x

X = 10151 = 10150

2). Answer c

(729)2 × (117)2 ÷ (13)2 ÷ 35 = 3x

312 × (117*117) / (13*13) ÷ 35 = 3x

312 × 81 ÷ 35 = 3x

312 × 34 ÷ 35 = 3x

312 + 4 -5 = 3x

311 = 3x

X = 11

3). Answer a

27 % of 300 + 43 % of 400 – 7 % of 600 = x

X = (27/100)*300 + (43/100)*400 – (7/100)*600

X = 81 + 172 – 42

X = 211 = 210

4). Answer b

45 % of 900 + 71 % of 800 – 24 % of 750 = x

X = (45/100)*900 + (71/100)*800 – (24/100)*750

X = 405 + 568 – 180

X = 793 = 795

5). Answer e

(9/28)*(392/72)*915 – 439 + (69/100)*1400 = x

X = 1600 – 439 + 966

X = 2130

Direction (6-10)

6). Answer a

The pattern is, *1/2, *3/2, *5/2, *7/2, *9/2,..

The answer is, 2992.5

7). Answer e

The pattern is, *1 + 22, *2 + 32, *3 + 42, *4 + 52, *5 + 62,..

The answer is, 2821

8). Answer d

The pattern is, *2 + 1, *4 + 3, *6 + 5, *8 + 7,..

The answer is, 5375

9). Answer c

The pattern is, ÷ 2, ÷ 3, ÷ 4, ÷ 5,..

The answer is, 26.25

10). Answer b

The difference of difference is, 92, 82, 72, 62,..

The answer is, 1511

 

11). Answer b

The ratio of the present age of Pavithra and Nivetha = 3: 5(3x, 5x)

7 years hence, their ratio = 11: 16

According to the question,

(3x + 7)/(5x + 7) = (11/16)

48x + 112 = 55x + 77

35 = 7x

X = 5

The present age of Pavithra and Nivetha = 15 and 25

Required ratio = (15 – 5): (25 – 5) = 10: 20 = 1: 2

12). Answer a

15m * 24 = 18w * 36

5m = 9w

10m + 8w = 18w + 8w = 26 w

Women        days

18               36

26               ?

(18*36) = (26*x)

X = (18*36)/26 = 324/13 = 24 12/13 days

13). Answer c

Let us assume the cost price be Rs. 100,

MP = (130/100)*CP = (130/100)*100 = 130

SP = 130*(75/100) = Rs. 97.5

Loss % = (2.5/100)*100 = 2.5 % loss

14). Answer d

A + B + C = Rs. 33250

(3/7)* A = (2/3)* B

(A/B) = (2/3) * (7/3) = 14/9

(1/4)* B = (5/8)* C

(B/C) = (5/8) * (4/1) = 5/2

 

133’s = 33250

1’s = 250

70’s = Rs. 17500

15). Answer a

The share of A, B and C,

= > [45000*3 + 60000*9]: [65000*3 + 60000*9]: [70000*7 + 55000*5]

= > 675000: 735000: 765000

= > 45: 49: 51

Total profit = Rs. 114405

145’s = 114405

1’s = 789

The share of A = 789*45 = Rs. 35505

Direction (16-20)

16). Answer b

The total export of Cotton in the period of March to August

= > [27 + 32 + 36 + 26 + 38 + 24]*(29/100)

= > 183*(29/100)

= > 53.07 billion dollars

Required average = 53.07/6 = 8.845 billion dollars

17). Answer c

Total export of Plastics and Chemical products in the month of May and June together

= > 36*(30/100) + 26*(30/100)

= > 10.8 + 7.8

= > 18.6 billion dollars

Total export of Iron and steel and Meat in the month of July and August together

= > 38*(41/100) + 24*(41/100)

= > 15.58 + 9.84

= > 25.42 billion dollars

Required % = (18.6/25.42)*100 = 73.17 % = 73 %

18). Answer a

The total exports of Meat in the month of March, May and July together

= > (27 + 36 + 38)*(17/100)

= > 17.17 billion dollars

The total exports of Iron and Steel in the month of April, June and August together

= > (32 + 26 + 24)*(24/100)

= > 19.68 billion dollars

Required difference = 19.68 – 17.17 = 2.51 billion dollars

19). Answer d

The total exports of Cotton in the month of July and August together

= > (38 + 24)*(29/100)

= > 17.98 billion dollars

The total exports of Chemical products in the month of March and April together

= > (27 + 32)*(18/100)

= > 10.62 billion dollars

Required ratio = 17.98: 10.62 = 899: 531

20). Answer c

Total exports of Cotton and Meat in the month of March and August together

= > (27 + 24)*[(29 + 17)/100]

= > 23.46 billion dollars

Total exports of Iron and Steel and Chemical products in the month of April and June together

= > (32 + 26)*[(24 + 18)/100]

= > 24.36 billion dollars

Required % = [(24.36 – 23.46)/24.36]*100 = 3.69 % = 4 % less
