| Before |
2 u |
11 u |
13 u |
| Change |
- 0.5 u |
- 60 |
|
| After |
1.5 u |
6 u |
|
Number of starfruits sold
=
14 x 2 u
= 0.5 u
Number of starfruits left
= 2 u - 0.5 u
= 1.5 u
Number of passion fruits left
= 4 x 1.5 u
= 6 u
Number of passion fruits sold
= 11 u - 6 u
= 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Number of starfruits and passion fruits at first
= 2 u + 11 u
= 13 u
= 13 x 12
= 156
Answer(s): 156
