q: Tom covers a distance of 8km in 50 minutes. If he covers 3km distance in 2/5th of time then, What speed should he maintain to cover the remaining distance in the remaining time?
Options:
(A) 15 Kmph
(B) 29 Kmph
(C) 25 Kmph
(D) 30 Kmph
(E) 34 Kmph
a: Stream of consciousness: Total distance = 8 Km
Total time = 50 Km
Time taken to cover the distance of 3 Km = 50*2/5 = 20 min = 1/3 hours
Remaining distance = 8 - 3 = 5 Km
Required speed = 5/1/3 = 15 Kmph The answer is (A).

question: A train 250 m long is running at a speed of 27 km/hr. In what time will it pass a bridge 200 m long?
Options:
(A) 40
(B) 45
(C) 50
(D) 55
(E) 60
answer: Stream of consciousness: Speed = 27 * 5/18 = 15/2 m/sec
Total distance covered = 250 + 200 = 450 m
Required time = 450 * 2/15 = 60 sec The answer is (E).

q: In how many different number of ways 7 men and 3 women can sit on a shopa which can accommodate persons?
Options:
(A) 200

question: The speed of a boat in still water is 60kmph and the speed of the current is 30kmph. Find the speed downstream and upstream?
Options:
(A) kmph
(B) kmph
(C) kmph
(D) kmph
(E) kmph
answer: Stream of consciousness: Speed downstream = 60 + 30 = 90 kmph
Speed upstream = 60 - 30 = 30 kmph The answer is (D).

q: During a sale, the price of a pair of shoes is marked down 10% from the regular price. After the sale ends, the price goes back to the original price. What is the percent of increase to the nearest percent from the sale price back to the regular price for the shoes?
Options:

(B) 10%
(C) 11%
(D) 15%
(E) 90%
a: Stream of consciousness: Assume the price = 100
Price during sale = 90
Price after sale = 100
Percent increase = 10/90*100 = 11% approx. The answer is (C).

(E) 5 days
a:
Stream of consciousness: The length of cloth painted by one man in one day = 48 / 4 2 = 6 m
No. of days required to paint 36 m cloth by 6 men = 72/ 6 6 = 2 day. The answer is (B).
