35 60% x 25 =
35 x 25 = 15
25 - 15 = 10
10% =
10100 =
110 The number of mangoes is 50 less than the number of oranges in the end. So, if another 50 mangoes are added, the number of mangoes and oranges in the end will be the same.
4 u + 10 + 50 = 9 u
4 u + 60 = 9 u
9 u - 4 u = 60
5 u = 60
1 u = 60 ÷ 5 = 12
Number of mangoes left
= 4 u + 10
= 4 x 12 + 10
= 48 + 10
= 58
Total number of fruits left
= 4 u + 10 + 9 u
= 13 u + 10
= 13 x 12 + 10
= 156 + 10
= 166
