Based on the stem we know that the amount sold in each month was:
May: x
June: 1.1x

stmt1:we can set up the the following equation: 1.1x - x = 27. We can solve this, sufficient
Stmt2: does not provide relevant info, insuff.

A is correct

St1: this gives diff between june and may as 27.by question stem we know that this diff is equal to 10%. using both the facts we can calculate number of hot dogs for each month hence this data is SUFFICIENT.

St2: given st does not give any absolute value info like st1 hence INSUFFICIENT.

Thus Ans choice A
