Number of mangoes at first in percent = 100%
Number of mangosteens at first in percent
= 100% + 60%
= 160%

160100 =
85Number of mangoes sold
= 20% x 5 u
=
20100 x 5 u
= 1 u
Number of more mangosteens than mangoes in the end
= 8 u - 4 u
= 4 u
4 u = 20
1 u = 20 ÷ 4 = 5
Total number of mangoes and mangosteens at first
= 8 u + 5 u
= 13 u
= 13 x 5
= 65
