We can also use estimation to solve this very quickly based on the principle that if a quantity decreases by x percent, it has to increase by a greater percent greater than x to reach the initial quantity.
Hence we can eliminated C,D, and E.
So A and B are contenders.
If something decreases 10%, you certainly wouldn't need increase it by 25% to get it back to the initial quantity. So we can eliminate A.
Hence, answer is B.
