A fruit seller had pomegranates and starfruits. The ratio of pomegranates to starfruits was 3 : 7. After
25 of the pomegranates and 24 starfruits were sold, there were 3 times as many pomegranates as starfruits left. How many pomegranates and starfruits were there at first?
| |
Pomegranates |
Starfruits |
Total |
| Before |
3 u |
7 u |
10 u |
| Change |
- 1.2 u |
- 24 |
|
| After |
1.8 u |
5.4 u |
|
Number of pomegranates sold
=
25 x 3 u
= 1.2 u
Number of pomegranates left
= 3 u - 1.2 u
= 1.8 u
Number of starfruits left
= 3 x 1.8 u
= 5.4 u
Number of starfruits sold
= 7 u - 5.4 u
= 1.6 u
1.6 u = 24
1 u = 24 ÷ 1.6 = 15
Number of pomegranates and starfruits at first
= 3 u + 7 u
= 10 u
= 10 x 15
= 150
Answer(s): 150
