**Quote:**

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?

Question stems asks us in what multiples of

addition of $500 and

subtraction of $300 each can result in $1200 after one month. Few inherent assumptions:

a. No lock on frequency on withdrawal and deposit, but as per question stem

summation of both needs to be as minimum as possible to reach $1200

b. initial amount of $0 at the start of transactions in the question stem.

Obviously for an amount to reach $1200 I need at least

3 multiples of $500 to reach $1500 and

then I need just 1 multiple of $300 to get $1200 (final amount).
