60% =

35 60% x 30 =
35 x 30 = 18
30 - 18 = 12
35% =
35100 =
720 The number of mangoes is 13 less than the number of chikoos in the end. So, if another 13 mangoes are added, the number of mangoes and chikoos in the end will be the same.
8 u + 12 + 13 = 13 u
8 u + 25 = 13 u
13 u - 8 u = 25
5 u = 25
1 u = 25 ÷ 5 = 5
Number of mangoes left
= 8 u + 12
= 8 x 5 + 12
= 40 + 12
= 52
Total number of fruits left
= 8 u + 12 + 13 u
= 21 u + 12
= 21 x 5 + 12
= 105 + 12
= 117
