A man walks a certain distance and rides back in 6 1⁄4h. He can walk both ways in 7 3⁄4h. How long it would take to ride both ways ?	Choose the correct choice from the following
A) 5 hours	B) 4 1⁄2 hours	C) 4 3⁄4 hours	D) 6 hours	E) None of these
We know that, the relation in time taken with two different modes of transport is   twalk both + tride both = 2 (twalk + tride)   31⁄4 + tride both = 2 × 25⁄4   ⇒ tride both = 25⁄2 - 31⁄4 = 19⁄4 = 43⁄4 hours   Answer 4 3⁄4 hours
