Q:

A) 120m | B) 150m |

C) 125m | D) None of these |

Answer: B) 150m

Explanation:

Explanation:

Let the length of the train e x meter, and let the speed of train be y km/h, then

$x=\left(y+3\right)\times \frac{5}{18}\times 36$ --------(1) and

$x=\left(y+6\right)\times \frac{5}{18}\times 30$ ---------(2)

From eq (1) and (2), we get

y = 12 km/h

Therefore, $x=(y+3)\times \frac{5}{18}\times 36$ => x= 150 m
