4 u |
1 u |
4 u - 31 |
140 |
Total number of fruits in the end
= 4 u + 1 u + 4 u - 31
= 9 u - 31
9 u - 31 = 140
9 u = 140 + 31
9 u = 171
1 u = 171 ÷ 9 = 19
Number of guavas at first
= 4 u - 31 + 47
= 4 x 19 + 16
= 92
The number of guavas and chikoos at first is the same.
Number of chikoos sold
= 92 - 19
= 73
Answer(s): 73
