A train passes a 110-meter long bridge in 12 seconds and a standard sign post in 7 seconds. Find the length of the train.
Correct Answer: Option D
Explanation:
Time taken to cross the bridge alone = 12 - 7 = 5 seconds. Speed of train = 110 / 5 = 22 m/s. Length of train = Speed * Time to cross sign post = 22 * 7 = 154 meters.
Time taken to cross the bridge alone = 12 - 7 = 5 seconds. Speed of train = 110 / 5 = 22 m/s. Length of train = Speed * Time to cross sign post = 22 * 7 = 154 meters.

A train 160 meters long running at 54 km/h crosses a platform in 24 seconds. Find the length of the platform.
Correct Answer: Option C
Explanation:
Speed of train = 54 * (5/18) = 15 m/s. Total distance covered in 24 seconds = 15 * 24 = 360 meters. Platform length = 360 - 160 = 200 meters.
Speed of train = 54 * (5/18) = 15 m/s. Total distance covered in 24 seconds = 15 * 24 = 360 meters. Platform length = 360 - 160 = 200 meters.

A man rows a boat 20 km downstream in 2 hours and returns upstream in 5 hours. Find the speed of the stream.
Correct Answer: Option B
Explanation:
Downstream speed = 20 / 2 = 10 km/h. Upstream speed = 20 / 5 = 4 km/h. Speed of stream = (10 - 4) / 2 = 6 / 2 = 3 km/h.
Downstream speed = 20 / 2 = 10 km/h. Upstream speed = 20 / 5 = 4 km/h. Speed of stream = (10 - 4) / 2 = 6 / 2 = 3 km/h.
