Money

Money is paid into an account in portions of $500 and paid out in portions of $300. If after a month the account grew by $1,200, what is the least possible number of transactions that could have been made?

IMO E

Three $500 in = $1500 and one $300 out = -$300 (Total $1200)

So total 4 transactions.

this question is not clear about how many money does the account have at the start of transaction so i will consider it zero
it has to paid in 3 time and paid out 1 time to get 1200 thus
is that E=4 the answer?
