Directions(1-5): What will come in place of question mark “?” in the following questions.

1. 339% of 803 + 77.8% of 1107 = ?
3002
3578
3451
3774
3770
Option B
339% of 803 + 77.8% of 1107 = ?
= (340×800)/100 + (78×1100)/100
= 2720 + 858 = 3578

2. 333.33 + 33.33 + 13 + 0.33 + 0.03 = ?
330.4
350.5
300.3
380.2
385.3
Option D
333.33 + 33.33 + 13 + 0.33 + 0.03 = ?
= 380.2

3. 525 – (13)² + 63 = (?)² + 95
17
12
15
18
14
Option D
525 – (13)² + 63 = (?)² + 95
(?)^2+95 = 525–169+63
(?)^2 = 419 –95
= √324
= 18

4. (62.5 × 12 × 3) ÷ 9 – 34 = (?)^3
8
11
6
5
2
Option C
(62.5 × 12 × 3) ÷ 9 – 34 = (?)^3
(?)^3 = 250–34
= (216)^1/3
= 6

5. √4624 + √841 +1 = 14 × ?
10
13
7
5
15
Option C
√4624 + √841 +1 = 14 ×?
68 + 29 + 1 = 14 ×?
= 7

6. Four examiners examine a certain number of answer papers in 10 days by working for five hours a day. For how many hours in a day would two examiners have to work in order to examine twice the number of answers papers in 20 days?
20 hours
10 hours
30 hours
50 hours
40 hours
Option B
Let the required hours per day are t hours.
10×4×5/n = 20×2×t/2n
=> t = 20/2
=> t = 10 hours

7. A man can row 40 Km upstream and 55 Km downstream in 13 h. Also, he can row 30 km upstream and 44 Km downstream in 10 h. Find the speed of the man in still water.
8 km/h
6 km/h
5 km/h
12 km/h
10km/h
Option A
40/x + 55/y = 13 …. (i)
30/x + 44/y = 10 …. (ii)
Solving the equations (i) and (ii), we get x = 5 and y = 11
speed of the man in still water
= 1/2 (x + y) = 1/2 (5 + 11)
= 16/2 = 8 km/h

8. Arun bought a computer with 15% discount on the labelled price. He sold the computer for Rs. 2880 with 20% profit on the labelled price. At what price did he buy the computer?
3540
2350
2040
2000
3000
Option C
120% of labelled price = 2880
85% of labelled price = (2880×85)/120
= 2040

9. Find the amount of debt that will be discharged by 9 equal installments of Rs. 220 each, if the debt is due in 6 years at 3 % p.a.
Rs. 1515
Rs. 1005
Rs. 1111
Rs. 1400
Rs. 1419
Option E
Amount of each installment
= 100 p/[ 100n+ n(n−1)r/2] => 220 = 100p/[100 × 6 + 6(6−1)3/2] => 220 = 100p/(600 + 45)
=>p = 220/100*645
= Rs. 1419

10. A committee of five persons is to be chosen from a group of 10 people. The probability that a certain married couple will either serve together or not at all is?
55/126
43/126
51/126
51/120
51/121
Option C
Five persons is to be chosen from a group of 10 people
= 10C5 = 252
Couple Serve together = 8C3 * 2C2 = 56
Couple does not serve = 8C5 = 56
Probability = 102/252
= 51/126
