A positive number consists of two digits. when the digit in the unit place is divided by the digit in the ten's place then the quotient is 2. If 27 is added to the number interchange their places. Find the number.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

the answer to your question is b.
