A fruit seller had starfruits and pomegranates. The ratio of starfruits to pomegranates was 3 : 7. After
25 of the starfruits and 32 pomegranates were sold, there were 3 times as many starfruits as pomegranates left. How many starfruits and pomegranates were there at first?
| |
Starfruits |
Pomegranates |
Total |
| Before |
3 u |
7 u |
10 u |
| Change |
- 1.2 u |
- 32 |
|
| After |
1.8 u |
5.4 u |
|
Number of starfruits sold
=
25 x 3 u
= 1.2 u
Number of starfruits left
= 3 u - 1.2 u
= 1.8 u
Number of pomegranates left
= 3 x 1.8 u
= 5.4 u
Number of pomegranates sold
= 7 u - 5.4 u
= 1.6 u
1.6 u = 32
1 u = 32 ÷ 1.6 = 20
Number of starfruits and pomegranates at first
= 3 u + 7 u
= 10 u
= 10 x 20
= 200
Answer(s): 200
