- 3x4 =
- 12 u |
- 15 |
- 7x1 =
- 7 u |
| After |

60% =
60100 =
35 60% x 25 =
35 x 25 = 15
25 - 15 = 10
35% =
35100 =
720 The number of kiwis is 15 less than the number of apples in the end. So, if another 15 kiwis are added, the number of kiwis and apples in the end will be the same.
8 u + 10 + 15 = 13 u
8 u + 25 = 13 u
13 u - 8 u = 25
5 u = 25
1 u = 25 ÷ 5 = 5
Number of kiwis left
= 8 u + 10
= 8 x 5 + 10
= 40 + 10
= 50
Total number of fruits left
= 8 u + 10 + 13 u
= 21 u + 10
= 21 x 5 + 10
= 105 + 10
= 115
