Number of apples left
= 33 + 99 - 33 - 33
= 66
3 u = 66
1 u = 66 ÷ 3 = 22
Total number of apples at first
= 10 u
= 10 x 22
= 220
Number of green apples at first
= 220 ÷ 2
= 110
Number of green apples removed at first
= 110 - 33
= 77
Total number of green apples removed
= 77 + 33
= 110
Answer(s): 110
