Rationale: 221 + 43 = 264/17 = 9 (Remainder)
The answer: (C)
Question: A no.when divided by 221 gives a remainder 43, what remainder will beobtained by dividingthe same no.17?
Options:
(A) 3
(B) 6
(C) 9
(D) 10
(E) 12

Reasoning: 44 + 28 + 10 = 82%
100 – 82 = 18%
700 * 18/100 = 126
Ans: (B)
Question: In a school of 700 boys, 44% of Muslims, 28% Hindus, 10% Sikhs and the remaining of other communities. How many belonged to the other communities?
Options:
(A) 173
(B) 126
(C) 153
(D) 143
(E) 133

Rationale: 12 m/s = 12 * 18/5 kmph
3 hours 45 minutes = 3 3/4 hours = 15/4 hours
Distance = speed * time = 12 * 18/5 * 15/4 km = 162 km.
The answer: (B)
Question: If a man can cover 12 metres in one second, how many kilometres can he cover in 3 hours 45 minutes?
Options:
(A) 118 km
(B) 162 km
(C) 1767 km
(D) 1887 km
(E) 177 km

Reasoning: D = 25 * 60 + 1500 = 3000 m
T = 3000/60 * 18/5 = 180 sec = 3 mins
Ans: (B)
Question: A train of 24 carriages, each of 60 meters length, when an engine also of 60 meters length is running at a speed of 60 kmph. In what time will the train cross a bridge 1.5 km long?
Options:
(A) 5 mins
(B) 3 mins
(C) 7 mins
(D) 9 mins
(E) 2 mins

Rationale: 1 to 11 = 11 * 50 = 550
1 to 5 = 5 * 49 = 245
5 to 11 = 7 * 52 = 364
5th = 245 + 364 – 550 = 59
The answer: (E)
Question: The average of 11 results is 50, if the average of first five results is 49 and that of the last seven is 52. Find the fifth result?
Options:
(A) 55
(B) 56
(C) 57
(D) 58
(E) 59

Rationale: D = 25 * 60 + 4500 = 6000 m
T = 6000/60 * 18/5 = 360 sec = 6 mins
The answer: (D)

Question: A train of 24 carriages, each of 60 meters length, when an engine also of 60 meters length is running at a speed of 60 kmph. In what time will the train cross a bridge 4.5 km long?
Options:
(A) 4
(B) 3
(C) 5
(D) 6
(E) 9
