Number of mangoes at first in percent = 100%
Number of starfruits at first in percent

= 20% x 10 u
=
20100 x 10 u
= 2 u
Number of more starfruits than mangoes in the end
= 13 u - 8 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Total number of mangoes and starfruits at first
= 13 u + 10 u
= 23 u
= 23 x 11
= 253
