4 u |
Number of grapes left
= 29 + 187 - 48 - 48
= 120
4 u = 120
1 u = 120 ÷ 4 = 30
Total number of grapes at first
= 9 u
= 9 x 30
= 270
Number of green grapes at first
= 270 ÷ 2
= 135
Number of green grapes removed at first
= 135 - 29
= 106
Total number of green grapes removed
= 106 + 48
= 154
Answer(s): 154
