Question: A train running at the speed of 60 km/hr crosses a pole in 9 seconds. Find the length of the train.
Options:
(A) 150 m
(B) 155 m
(C) 180 m
(D) 190 m
(E) 205 m
[CoT]: [Answer: Option A
Speed = 60*(5/18) m/sec = 50/3 m/sec
Length of Train (distance) = speed * Time
(50/3) * 9 = 150 meter]

Answer: (B)
Question: Rs.800 amounts to Rs.920 in 3 years at simple interest. If the interest is increased by 3%, it would amount to how much?
Options:
(A) 226
(B) Rs.992
(C) 665
(D) 771
(E) 211
[CoT]: [(800*3*3)/ 100 = 72
920 + 72 = 992]

Answer: (D)
Question: If P(A) = 8/15, P(B) = 4/15, and P(A B) = 16/15 Find P(B|A)
Options:
(A) 1/2
(B) 2/3
(C) 3/2
(D) 2
(E) 4/7
[CoT]: [P(B|A) = P(A B)/P(A)
P(B|A) = (16/15)/(8/15) = 2.]

Answer: (D)
Question:
A train 210 m long, running with a speed of 63 km/hr will pass a tree in?
Options:

(B) 16 sec
(C) 18 sec
(D) 12 sec
(E) 25 sec
[CoT]: [Speed = 63 * 5/18 = 35/2 m/sec
Time taken = 210 * 2/35 = 12 sec]
