Thats a lot of routes! :))
and its easy to get confused tracing the paths for the Y exit. We could calculate the number of cars from the X exit, the answer would be 100-(Xexits). It definitely is a lot more easier to calculate the number of cars in the X exit.

Assume 100 people come in through C

If you calculate the top half (25+12.5) then the bottom half is 50

87.5/100 = A)

Vishu, whats the OA?
