Number of oranges at first in percent = 100%
Number of mangoes at first in percent
= 100% + 20%
= 120%

65Number of oranges sold
= 60% x 5 u
=
60100 x 5 u
= 3 u
Number of more mangoes than oranges in the end
= 6 u - 2 u
= 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Total number of oranges and mangoes at first
= 6 u + 5 u
= 11 u
= 11 x 2
= 22
