A fruit seller had apples and persimmons. The ratio of apples to persimmons was 2 : 11. After
34 of the apples and 20 persimmons were sold, there were 2 times as many apples as persimmons left. How many apples and persimmons were there at first?

Apples |
Persimmons |
Total |
| Before |
2 u |
11 u |
13 u |
| Change |
- 1.5 u |
- 20 |
|
| After |
0.5 u |
1 u |
|
Number of apples sold
=
34 x 2 u
= 1.5 u
Number of apples left
= 2 u - 1.5 u
= 0.5 u
Number of persimmons left
= 2 x 0.5 u
= 1 u
Number of persimmons sold
= 11 u - 1 u
= 10 u
10 u = 20
1 u = 20 ÷ 10 = 2
Number of apples and persimmons at first
= 2 u + 11 u
= 13 u
= 13 x 2
= 26
Answer(s): 26
