710 x 80 = 56
80 - 56 = 24
20% =

15 The number of starfruits is 36 more than the number of chikoos in the end. So, if another 36 chikoos are added, the number of chikoos and starfruits in the end will be the same.
3 u + 24 + 36 = 8 u
3 u + 60 = 8 u
8 u - 3 u = 60
5 u = 60
1 u = 60 ÷ 5 = 12
Number of starfruits left
= 8 u
= 8 x 12
= 96
Total number of fruits left
= 3 u + 24 + 8 u
= 11 u + 24
= 11 x 12 + 24
= 132 + 24
= 156
