In the month of June, a street vendor sold 10% more hot dogs than he sold in the month of May. How many total hot dogs did the vendor sell in May and June?
(1) The vendor sold 27 more hot dogs in June than in May.
(2) In July, the vendor sold 20% more hot dogs than he sold in May.
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

87% (00:33) correct
