The difference in the amounts between Neave and his brother at first and in the end remains unchanged after each received an equal amount of allowance.
Difference in the amounts between Perry and his brother
= 2 u - 1 u
= 1 u
1 u = 222
Allowance that each of them received
= 1 u - 40
= 222 - 40
= $182
Answer(s): $182
