21. Answer: Option

B Explanation

22. Answer: Option D Explanation:

23) Answer: Option D

Explanation: 60 + 5 * 12 / (180/3) = 60 + 5 * 12 /

(60) = 60 + (5 * 12)/60 = 60 + 1 = 61. 24) Answer: Option C Explanation: 0.003 * ? * 0.0003 = 0.00000027

3/1000 * ? * 3/10000 = 3/1000 * 3/1000 * 3/100

? = 3/10 = 0.3 25) Answer: Option E Explanation:

(242 + 144 / 3) / 36 = (24 * 24 + 48)/36

= [12(48 + 4)]/(12 * 3) = 52/3 = 17 1/3

28) Answer: 'C' Total distance = 8 Km Total time = 50 Km Time taken to cover the distence of 3 Km

= 50*2/5 = 20 min = 1/3 hours Remaining

distance = 8 - 3 = 5 Km Required speed =

5/1/3 = 15 Kmph

29) Answer: 'C' For 2 years = (1002D)/R2 = (1002 × 45)/(5 × 5) = (10000 × 45)/25

= Rs.18000/-

30) Answer: Option 'D' A = Rs.2000/- , that is 2 parts B = Rs.3000/- , that is 3 parts C = Rs.4000/- , that is 4 parts Total 9 parts -------> profit (4500/-) ----->1 part -------->Rs.500/- then A's share 2 parts -----> Rs.1000/-

31) Answer: Option 'B' Total Length = platform Length+ Train Length Total Length= 500m D = S * T 500 = 72 * time 500 = 72 * 5/18 * time Time = 25Sec 32) Answer: Option 'C' Actual total weight is (20X 58.4 - 56 + 65)

= 1177 Kgs Actual average weight is 1177/20 = 58.85kgs 33) Answer: Option 'A' Second side = √172-

82 = √289-64 = 15 Cm Perimeter = 2 (l+b) = 2(8+5) Cm = 2(23) =

46 Cm 34) Answer: Option 'C'

Total no'of arrangements 5P5 = 5! = 120 no'of

arrangements start with AE=1 × 6 = 6 no'of

arrangements which do not start with AE = 120

- 6 = 114. 35) Answer: Option 'D'

Cost of 3 chairs + 10 tables = Rs.9856

Multiplying each term by ‘2’, we get Cost of 6 chairs + 20 tables = Rs.9856 x 2 =

Rs.19712.

36) Answer: Option

'B' 2 years = Rs.120/-

37) Answer: Option 'A'

A:B:C = 6:2:1 Total parts = 9 A's share is = 6 parts

9 -----> Rs.900/- 6 -----> Rs.600/-

year = 120/2 Rate of Interest = 1%

100/1% * 120/2 = Rs.6000/-

P = Rs.6000/-

38) Answer: Option B Explanation: Let A's age 10 years ago = x years.

Then, B's age 10 years ago = 2x years.

(x + 10) / (2x+ lO) = 3/4 => x = 5. So, the total of their present ages =(x + 10 + 2x + 10) = (3x + 20) = 35 years.

39) Answer: Option 'B' Man's rate down stream = 8 + 2 = 10 kmph

Man's rate upstream = 8 - 2 = 6 kmph Let the required distance be X

km Then X/10 + X/6 = 2 3X +

5X = 60 8X = 60 X = 7.5 km

40) Answer: Option 'A'

Total = 100 %, First person got 60% second person got remaining 40 %

of votes. than 40 % = 280
