Options:
(A) 1000
(B) 1100
(C) 1200
(D) 900
(E) 10000

Options:
(A) 10
(B) 32
(C) 36
(D) 19
(E) 20

A train running at the speed of 90 km/hr crosses a pole in 12 seconds. Find the length of the train?
Options:
(A) 150
(B) 872
(C) 287
(D) 288
(E) 300
--
Speed = 90*(5/18) m/sec = 75/3 m/sec
Length of Train (Distance) = Speed * Time
(75/3) * 12 = 300 meter So the answer is: (E).
