PSLEA fruit seller had the same number of kiwis, pears and guavas at first. After 40 guavas, some kiwis and pears were sold, there were 160 fruits left. There were 3 times as many kiwis as pears left. The number of guavas left was 22 fewer than the number of kiwis left. How many pears were sold?

3 u |
1 u |
3 u - 22 |
160 |
Total number of fruits in the end
= 3 u + 1 u + 3 u - 22
= 7 u - 22
7 u - 22 = 160
7 u = 160 + 22
7 u = 182
1 u = 182 ÷ 7 = 26
Number of guavas at first
= 3 u - 22 + 40
= 3 x 26 + 18
= 96
The number of guavas and pears at first is the same.
Number of pears sold
= 96 - 26
= 70
Answer(s): 70
