1. A train passes a platform in 40 sec and a woman standing on the platform in 30 sec. If the speed of the train is 108 km/hr, what is the length of the platform?
- A. 100m
- B. 100m
- C. 100m
- D. 100m
Answer: Option B
Explanation:
Length of train=108×30×(5/18)=900m
Length of train+platform=108×(5/18)×40=1200m
So, Length of platform=1200-900=300m
