95. The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:

By /
[A]. 70 km/hr
[B]. 75 km/hr
[C]. 84 km/hr
[D]. 87.5 km/hr
✅ The correct answer is option D.
Let the speed of two trains be 7x and 8x km/hr.

Then, 8x =

400

= 100

4

x =

100

= 12.5

8

Speed of first train = (7 x 12.5) km/hr = 87.5 km/hr.
