Number of pomegranates and starfruits sold
= 128 - 47
= 81
3 u + 1 p = 81
1 p = 81 - 3 u --- (1)
1 u + 1 p = 47
1 p = 47 - 1 u --- (2)
(2) = (1)
47 - 1 u = 81 - 3 u
3 u - 1 u = 81 - 47
2 u = 34
1 u = 34 ÷ 2 = 17
Number of pomegranates at first
= 4 u
= 4 x 17
= 68
Number of starfruits at first
= 128 - 68
= 60
Fraction of the fruits that were starfruits at first
