A fruit seller had pears and starfruits. The ratio of pears to starfruits was 3 : 8. After
12 of the pears and 32 starfruits were sold, there were 4 times as many pears as starfruits left. How many pears and starfruits were there at first?

Pears |
Starfruits |
Total |
| Before |
3 u |
8 u |
11 u |
| Change |
- 1.5 u |
- 32 |
|
| After |
1.5 u |
6 u |
|
Number of pears sold
=
12 x 3 u
= 1.5 u
Number of pears left
= 3 u - 1.5 u
= 1.5 u
Number of starfruits left
= 4 x 1.5 u
= 6 u
Number of starfruits sold
= 8 u - 6 u
= 2 u
2 u = 32
1 u = 32 ÷ 2 = 16
Number of pears and starfruits at first
= 3 u + 8 u
= 11 u
= 11 x 16
= 176
Answer(s): 176
