A man is riding a bike with front and back wheel circumference of 40 inches and 70 inches respectively. If the man rides the bike on a straight road without slippage, how many inches will the man have travelled when the front wheel has made 15 revolutions more than the back wheel? Choose the most appropriate option.
A) 3388	B) 2882	C) 1400	D) 277	E) 2282
Explanation:   Given the ratio of the circumference of front wheel is 40 inches and back wheel is 70 inches   Distance covered = Circumference of the wheel Ã— No. of Revolutions made by the wheel   If n is the number of revolutions made by back wheel, the number of revolutions made by front wheel is n+15   Distance covered by both the wheels is the same   40*(n+3)=70n   n=20   Front wheel : Back Wheel   Circumference 40 : 70   Revolutions 35 : 20   Distance covered \small \Rightarrow 40Ã—35 = 70Ã—20 = 1400 inches.   Answer: 1400
