| After |

75% =
75100 =
34 75% x 100 =
34 x 100 = 75
100 - 75 = 25
30% =
30100 =
310 The number of chikoos is 65 less than the number of mangoes in the end. So, if another 65 chikoos are added, the number of chikoos and mangoes in the end will be the same.
5 u + 25 + 65 = 14 u
5 u + 90 = 14 u
14 u - 5 u = 90
9 u = 90
1 u = 90 ÷ 9 = 10
Number of chikoos left
= 5 u + 25
= 5 x 10 + 25
= 50 + 25
= 75
Total number of fruits left
= 5 u + 25 + 14 u
= 19 u + 25
= 19 x 10 + 25
= 190 + 25
= 215
