| Before |
3 u |
7 u |
10 u |
| Change |
- 1.8 u |
- 69 |
|
| After |
1.2 u |
2.4 u |

Number of passion fruits sold
=
35 x 3 u
= 1.8 u
Number of passion fruits left
= 3 u - 1.8 u
= 1.2 u
Number of kiwis left
= 2 x 1.2 u
= 2.4 u
Number of kiwis sold
= 7 u - 2.4 u
= 4.6 u
4.6 u = 69
1 u = 69 ÷ 4.6 = 15
Number of passion fruits and kiwis at first
= 3 u + 7 u
= 10 u
= 10 x 15
= 150
Answer(s): 150
