Correct Answer: 7.2 seconds
Solution : Given: The distance of the train is 100 m. The speed of the train is 50 km/h. We know that, $\text{Time}=\frac{\text{Distance}}{\text{Speed}}$ To convert km/h into m/s, multiply with $\frac{5}{18}$, we get, $50\times \frac{5}{18}=\frac{125}{9}$ m/s So, the train takes time to cross the pillar = $\frac{100}{\frac{125}{9}}$ = $\frac{36}{5}=7.2$ seconds Hence, the correct answer is 7.2 seconds.
