Two trains 300m and 400m long run at the speeds of 40 kmph and 50kmph respectively in opposite Directions on parallel tracks. The time taken to cross each other?
A. 20sec B. 25secs
C. 26sec D. 28sec
Answer and Explanation
Answer:D
Explanation: Length of two Trains = 300m + 400m = 700m Total Speed= 40 Kmph + 50 Kmph (Opposite Direction) = 90 Kmph Time = Distance/Speed Time = 700/ 90 Time = 28Sec

A train crosses a tree in 120sec, while it crosses a 700m long platform in 190sec. the length of the Train is:

A. 1500m B. 1400m
C. 1300m D. 1200m
Answer and Explanation
Answer:D
Explanation: In 190Sec Cross a 700m Platform I.e., Length of Train + Length of Platform. 190 Sec- 120Sec = 700m 70Sec= 700m Speed= 10 M/Sec In 120 Sec The length wil be 1200m.
