The correct option is (C).
Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance travelled by the train in 7 seconds by applying the following formula: Distance= Speed x Time Speed is given in Km/hr so we will convert it into m/s as answers are given in meters. Speed=90* = 25 m/s Time = 7 seconds Distance = 25 * 7= 175 meters Problem on Trains Aptitude Test 1 Problem on Trains Aptitude Test 2 Problem on Trains Aptitude Test 3 Problem on Trains Aptitude Test 4 Problem on Trains Aptitude Test 5 Problem on Trains Aptitude Concepts ## 16) Time and Work Aptitude1) Worker A completes a task in 8 days and worker B completes the same task in 10 days.
