Total |
| Before |
2 u |
7 u |
9 u |
| Change |
- 1.6 u |
- 116 |
|
| After |
0.4 u |
1.2 u |
|
Number of passion fruits sold
=
45 x 2 u
= 1.6 u
Number of passion fruits left
= 2 u - 1.6 u
= 0.4 u
Number of kiwis left
= 3 x 0.4 u
= 1.2 u
Number of kiwis sold
= 7 u - 1.2 u
= 5.8 u
5.8 u = 116
1 u = 116 ÷ 5.8 = 20
Number of passion fruits and kiwis at first
= 2 u + 7 u
= 9 u
= 9 x 20
= 180
Answer(s): 180
