A stallholder had the same number of mangosteens, peaches and chikoos at first. After 146 chikoos, some mangosteens and peaches were thrown away, there were 121 fruits left. There were five times as many mangosteens as peaches left. The number of chikoos left was 22 less than the number of mangosteens. How many peaches were thrown away?

5 u |
1 u |
5 u - 22 |
121 |
Total number of fruits in the end
= 5 u + 1 u + 5 u - 22
= 11 u - 22
11 u - 22 = 121
11 u = 121 + 22
11 u = 143
1 u = 143 ÷ 11 = 13
Number of chikoos at first
= 5 u - 22 + 146
= 5 x 13 - 22 + 146
= 65 - 22 + 146
= 189
The number of peaches and chikoos at first was the same.
Number of peaches thrown away
= 189 - 1 u
= 189 - 13
= 176
Answer(s): 176
