A motorcyclist goes from Bombay to Pune, a distance of 192 kms at an average of 32 kmph speed. Another man starts from Bombay by car 2 hours after the first, and reaches Pune hour earlier. What is the ratio of the speed of the motorcycle and the car?
Options:
(A) 1:2
(B) 1:5
(C) 1:9
(D) 1:3
(E) 1:1

T = 192/32 = 6 h
T = 6 - 3 = 3
Time Ratio = 6:3 = 2:1
Speed Ratio = 1:2 So the answer is: (A).

In Hockey game, one player throws two fair, six-sided die at the same time. If the player receives at least a five or a one on either die, that player wins. What is the probability that a player wins after playing the game once?
Options:
(A) 1/3
(B) 4/9

(D) 2/3
(E) 3/4

In Hockey game, Probably the easiest approach would be to find the probability of the opposite event and subtract it from 1:
P(win) = 1- P(not win) = 1 - 4/6*4/6 = 5/9. So the answer is: (C).

The edges of cuboid are 4 cm; 5 cm and 6 cm. Find its surface area?
Options:
(A) 228
(B) 148

(E) 222

2(4*5 + 5*6 + 4*6) = 148 So the answer is: (B).

If 12 men can reap 120 acres of land in 16 days, how many acres of land can 36 men reap in 32 days?
Options:
(A) 269
(B) 512
(C) 369
(D) 720
(E) 450
12 men 120 acres 16 days
36 men ? 32 days

120 * 3 * 2
120 * 6 = 720 So the answer is: (D).
