There is a 50m long army platoon marching ahead. The last
person in the platoon wants to give a letter to the first
person leading the platoon. So while the platoon is marching
he runs ahead, reaches the first person and hands over the
letter to him and without stopping he runs and comes back to
his original position.

In the mean time the whole platoon has moved ahead by 50m.

The question is how much distance did the last person cover
in that time. Assuming that he ran the whole distance with
uniform speed.

Answer Posted / saurabh shuka

he will cover 150m becoz when he was at the last position
the platoon was 50m ahead and when he reach to the first
platoon he coverd 50+25=75m and same distance he will cover
to come back bcoz at last position the platoon moved more
50m
