Answer is 350 km.

Explanation:-
A _________X________M_________________(X+70)______________D
Let distance is (2X + 70) Km.
In whole, Journey, Time remain same for the both trains,
So, Speed of Delhi train /Speed of Aligarh train,
= Distance covered by Delhi train/ Distance covered by Aligarh train.
21/14 = (X +70)/X
21X = 14X + 980
7X = 980
X = 140
Total Distance = 2X + 70 = 2 x 140 + 70 = 350 km.

Then, the distance between two station is 350 km.

Hence, the correct answer is option (4) 350 km.
