In a cookie-eating contest, there are 200 cookies provided to each contestant. Both start at the same time. Contestant A wins the contest by eating 20 more cookies than Contestant B. How many cookies did the winner eat altogether?
(1) Contestant A ate his cookies at a constant rate of 20 cookies per minute and Contestant B ate her cookies at a constant rate of 15 cookies per minute.
(2) Contestant A is younger than Contestant B.
The OA (Statement 1 is sufficient) indicates that in 4 minutes there will be a gap of twenty cookies. I don't agree. The question doesn't indicate when the contestants should stop. In this sense, A could have eaten 140 cookies in 7 minutes ,and B could have eaten 120 cookies in 8 minutes.
IMO, the answer is E.
OA is A.
