Two trains A and B started from stations P and Q respectively towards each other. Train A started at 7 p.m. at a speed of 60 km / hr and train B started at 4 a.m. (next day) at a speed of 90 km / hr. The distance between the two stations P and Q is 800 km.
How far from station Q will the two trains meet?

Correct option is C

Distance of train A = 60 x 9 = 540 km
Distance of train B = 800-540 = 260 km
Time = 260/(60+90) = 260/150 h
From station Q two trains meet = 90 x 26/15 = 156 km
