Kiran travels from A to B by car and returns from B to A by cycle in 7 hours. If he travels both ways by car he saves 3 hours. What is the time taken to cover both ways by cycle?  Pick one:
A) 10 hours  B) 23 hours  C) 18 hours  D) 20 hours  E) 12 hours
Let the time taken to cover from A to B in car and cycle be x hours and y hours respectively.   x + y = 7 --- (1) ; 2x = 4 --- (2)   solving both the equations, we get y = 5   So, time taken to cover both ways by cycle = 2y hours =10 hours.   10 hoursnswer: 10 hours
