Data Sufficiency

Beginning in January of last year, Carl made deposits of $120 into his account on the 15th of each month for several consecutive months and then made withdrawals of $50 from the account on the 15th of each of the remaining months of last year. There were no other transactions in the account last year. If the closing balance of Carl's account for May of last year was $2,600, what was the range of the monthly closing balances of Carl's account last year?
(1) Last year the closing balance of Carl's account
for April was less than $2,625.
(2) Last year the closing balance of Carl's account
for June was less than $2,675.

When you read these questions try to take small bites out of them. Make sure you understand the small clauses before moving onto the next one. This particular question really just requires you to figure out the month he went from saving to spending and both together give you the specific month.
