A fruit seller had mangoes and starfruits. The ratio of mangoes to starfruits was 3 : 11. After
34 of the mangoes and 190 starfruits were sold, there were 2 times as many mangoes as starfruits left. How many mangoes and starfruits were there at first?

Mangoes |
Starfruits |
Total |
| Before |
3 u |
11 u |
14 u |
| Change |
- 2.25 u |
- 190 |
|
| After |
0.75 u |
1.5 u |
|
Number of mangoes sold
=
34 x 3 u
= 2.25 u
Number of mangoes left
= 3 u - 2.25 u
= 0.75 u
Number of starfruits left
= 2 x 0.75 u
= 1.5 u
Number of starfruits sold
= 11 u - 1.5 u
= 9.5 u
9.5 u = 190
1 u = 190 ÷ 9.5 = 20
Number of mangoes and starfruits at first
= 3 u + 11 u
= 14 u
= 14 x 20
= 280
Answer(s): 280
