q: A goods train runs at the speed of 72 km/hr and crosses a 250 m long platform in 26 sec. What is the length of the goods train?
Options:
(A) 49 sec
(B) 50 sec
(C) 48 sec
(D) 43 sec
(E) 32 sec
a: Stream of consciousness: D = 540 + 180 = 720
S = 54 * 5/18 = 15 mps
T = 720/15 = 48 se The answer is (C).

(C) 33
(D) 36
(E) 28
a: Stream of consciousness: The average of 7 consecutive numbers will be the 4th number which is given to be = 33 5th number = 34, 6th number = 35, 7th number = 36 The answer is (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 1.1 km long?
Options:
(A) 2 mins 14 sec
(B) 2 mins 34 sec
(C) 156 sec
(D) 134 sec
(E) 2 mins 44 sec
answer: Stream of consciousness: D = 25 * 60 + 1100 = 2600 m
T = 2600/60 * 18/5 = 156 se The answer is (C).

question: A die is thrown. If G is the event 'the number appearing is a multiple of 3' and H be the event
'the number appearing is even' then find whether G and H are independent ?
Options:
(A) G and H are not independent events.
(B) G and H are independent events.
(C) Only G independent event
(D) Only H independent event
(E) None
answer:
Stream of consciousness: We know that the sample space is S = {1, 2, 3, 4, 5, 6}
Now G = { 3, 6}, F = { 2, 4, 6} and E n F = {6}
Then P(G) = 2/6 = 1/3
P(H) = 3/6 = 1/2 and P(G H) = 1/6
P(G n H) = P(G). P (H)
G and H are independent events. The answer is (B).
