A store owner has 50 less mangoes than chikoos. After he sold 60% of the mangoes and 35% of the chikoos, he is left with 10 less mangoes than chikoos. What fraction of the fruits left were mangoes?

Mangoes |
Chikoos |
Comparing mangoes and chikoos at first |
|
50 less |
Before |
5x4 = 20 u |
+ 50 |
20x1 = 20 u |
Change |
- 3x4 = - 12 u |
- 30 |
- 7x1 = - 7 u |
After |
2x4 = 8 u |
+ 20 |
13x1 = 13 u |
Comparing mangoes and chikoos in the end |
10 less |

60% =
60100 =
35 60% x 50 =
35 x 50 = 30
50 - 30 = 20
35% =
35100 =
720 The number of mangoes is 10 less than the number of chikoos in the end. So, if another 10 mangoes are added, the number of mangoes and chikoos in the end will be the same.
8 u + 20 + 10 = 13 u
8 u + 30 = 13 u
13 u - 8 u = 30
5 u = 30
1 u = 30 ÷ 5 = 6
Number of mangoes left
= 8 u + 20
= 8 x 6 + 20
= 48 + 20
= 68
Total number of fruits left
= 8 u + 20 + 13 u
= 21 u + 20
= 21 x 6 + 20
= 126 + 20
= 146
