A fruit seller had starfruits and apples. The ratio of starfruits to apples was 2 : 11. After
14 of the starfruits and 26 apples were sold, there were 3 times as many starfruits as apples left. How many starfruits and apples were there at first?

Starfruits |
Apples |
Total |
| Before |
2 u |
11 u |
13 u |
| Change |
- 0.5 u |
- 26 |
|
| After |
1.5 u |
4.5 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 apples left
= 3 x 1.5 u
= 4.5 u
Number of apples sold
= 11 u - 4.5 u
= 6.5 u
6.5 u = 26
1 u = 26 ÷ 6.5 = 4
Number of starfruits and apples at first
= 2 u + 11 u
= 13 u
= 13 x 4
= 52
Answer(s): 52
