(C) 1/44
(D) 1/264
(E) 1/1320
a: Stream of consciousness: It doesn't matter which type of card you choose, so:
Probability of choosing 1st card: 3/12

Multiply and you get 1/264 The answer is (D).

question: Two trains are moving at 40 kmph and 70 kmph in opposite directions. Their lengths are 150 m and 100 m respectively. The time they will take to pass each other completely is?
Options:
(A) 41/2 sec
(B) 5/2 sec
(C) 61/2 sec
(D) 71/6 sec
(E) 49/6 sec
answer: Stream of consciousness: 70 + 40 = 110 * 5/18 = 275/9mps
D = 150 + 100 = 250 m
T = 250 * 9/275 = 49/6 sec The answer is (E).
