Options:
(A) 35000
(B) 40000
(C) 50000
(D) 60000
(E) None
a: Stream of consciousness: Suppose Q invested Rs. y. Then, 40000/y = 2/3 or y = [40000 x 3 / 2] = 60000. The answer is (D).


question: A train 260 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?
Options:
(A) 40 sec
(B) 50 sec
(C) 32 sec
(D) 49 sec
(E) 60 sec
answer: Stream of consciousness: Speed = 45 * 5/18 = 25/2 m/sec
Total distance covered = 260 + 140 = 400 m
Required time = 400 * 2/25 = 32 se The answer is (C).

(D) E3
(E) F2
a: Stream of consciousness: Answer: Option C
The letters decrease by 1; the numbers are multiplied by 2. The answer is (C).


question: A train running at the speed of 60 km/hr crosses a pole in 12 sec. What is the length of the train?
Options:
(A) 118
(B) 150
(C) 277
(D) 200
(E) 191
answer: Stream of consciousness: Speed = 60 * 5/18 = 50/3 m/sec
Length of the train = speed * time = 50/3 * 12 = 200 m The answer is (D).


q: Look at this series: 53, 53, 48, 48, 43, 43, ... What number should come next?
