Correct Answer: 250


Solution : Given: The speed of trains running in the same direction is 70 km/hr and 34 km/hr.
Time is taken to cross each other = 25 seconds
Relative speed of trains = 70 – 34 = 36 km/hr
= 36 × $\frac{5}{18}$ m/s
= 10 m/s
We know, Distance = Speed × Time
So, Distance = 10 × 25 = 250 metres
$\therefore$ The combined length of both trains = 250 metres
Hence, the correct answer is 250.
