Number of oranges at first in percent = 100%
Number of mangoes at first in percent
= 100% + 30%
= 130%

= 70% x 10 u
=
70100 x 10 u
= 7 u
Number of more mangoes than oranges in the end
= 13 u - 3 u
= 10 u
10 u = 40
1 u = 40 ÷ 10 = 4
Total number of oranges and mangoes at first
= 13 u + 10 u
= 23 u
= 23 x 4
= 92
Answer(s): 92
