Number of mangosteens at first in percent = 100%
Number of starfruits at first in percent
= 100% + 30%
= 130%

1310Number of mangosteens sold
= 10% x 10 u
=
10100 x 10 u
= 1 u
Number of more starfruits than mangosteens in the end
= 13 u - 9 u
= 4 u
4 u = 8
1 u = 8 ÷ 4 = 2
Total number of mangosteens and starfruits at first
= 13 u + 10 u
= 23 u
= 23 x 2
= 46
