Mr Tan had thrice as many apples as pears at his stall at first. After he sold 129 apples and threw away 8 rotten pears, he had only half as many apples as pears left. How many pears did he have left?
Before -
After – Threw 8 pears, sold 129 apples, left with half as many apples as pears.
Apples sold
5 units + 8 + 8 + 8 ----- 129
5 units + 24 ----- 129
5 units ----- 129 –24
5 units ----- 105
1 unit ----- 105 divided by 5 = 21
Pears left
2 units ----- 21 x 2 = 42
Answer: He had 24 pears left.
