Question 4
Allan and Benny are computing the sum of a three-digit number and a two-digit number. The computation of Allan is correct with an answer of 136, while Benny is not doing it correctly because of a misalignment of digits in the vertical format mistakenly adding the tens digit of three-digit number with the units digit of the two-digit number and obtaining the tens digit in the sum. This is followed by adding the hundreds digit of the three-digit number and the tens digit of the two-digit number to get the hundreds digit in the sum with the final answer becoming 244. What is the difference between the three-digit number and the two-digit number?
