A man sitting in a train is counting the pillars of electricity. The distance between two pillars is 60 meters, and the speed of the train is 42 km/hr. In 5 hours, how many pillars will he count?
A. 3501
B. 3600
C. 3800
D. None of these
Answer: Option A
Solution(By Examveda Team)
Distance covered by the train in 5 hours= (42 × 5) km
= 210 km
= 210000 m
∴ Number of pillars counted by the man
= $$\left( {\frac{{210000}}{{60}} + 1} \right)$$
= 3500 + 1
= 3501
