| Before |
4x5 =
20 u |
+ 64 |
10x2 =
20 u |
| Change |
- 3x5 =
- 15 u |
- 48 |
- 1x2 =
- 2 u |
| After |
1x5 =
5 u |
+ 16 |
9x2 =
18 u |
Comparing kiwis
and mangoes in the end |
36 less |

75% =
75100 =
34 75% x 64 =
34 x 64 = 48
64 - 48 = 16
10% =
10100 =
110 The number of kiwis is 36 less than the number of mangoes in the end. So, if another 36 kiwis are added, the number of kiwis and mangoes in the end will be the same.
5 u + 16 + 36 = 18 u
5 u + 52 = 18 u
18 u - 5 u = 52
13 u = 52
1 u = 52 ÷ 13 = 4
Number of mangoes left
= 18 u
= 18 x 4
= 72
Total number of fruits left
= 5 u + 16 + 18 u
= 23 u + 16
= 23 x 4 + 16
= 92 + 16
= 108
