Sir ,Please explain the trick to solve the RS Aggarwal Question No 50,51 in which a speed not given
doubt in question no. 11 --- 72 kmph is the speed of train and 6 kmph is speed of man, so if we go by relative speed method (two body moving in same direction : we take difference of their speed) so here (72 - 6) i.e 56 correct me if m wrong
sahi h bhai vo.... relative speed hi to 72 h, train ki speed 72 thode hi h,vo to solve hi karni h.... isiliye relative speed=72=(speed of train-speed of man) ka use karke nikaala h....dhyan se dekho bhai...

I think Dinesh is right. Train's speed is 72 and relative speed would be 72-8 =66 as both are moving in the same direction, the speed of the train would be relatively slower. Please see and help.
