A fruit seller had kiwis and starfruits. The ratio of kiwis to starfruits was 4 : 11. After
45 of the kiwis and 86 starfruits were sold, there were 3 times as many kiwis as starfruits left. How many kiwis and starfruits were there at first?

Kiwis |
Starfruits |
Total |
| Before |
4 u |
11 u |
15 u |
| Change |
- 3.2 u |
- 86 |
|
| After |
0.8 u |
2.4 u |
|
Number of kiwis sold
=
45 x 4 u
= 3.2 u
Number of kiwis left
= 4 u - 3.2 u
= 0.8 u
Number of starfruits left
= 3 x 0.8 u
= 2.4 u
Number of starfruits sold
= 11 u - 2.4 u
= 8.6 u
8.6 u = 86
1 u = 86 ÷ 8.6 = 10
Number of kiwis and starfruits at first
= 4 u + 11 u
= 15 u
= 15 x 10
= 150
Answer(s): 150
