A fruit seller had persimmons and apples. The ratio of persimmons to apples was 3 : 11. After
35 of the persimmons and 148 apples were sold, there were 3 times as many persimmons as apples left. How many persimmons and apples were there at first?

Persimmons |
Apples |
Total |
Before |
3 u |
11 u |
14 u |
Change |
- 1.8 u |
- 148 |
|
After |
1.2 u |
3.6 u |
|
Number of persimmons sold
=
35 x 3 u
= 1.8 u
Number of persimmons left
= 3 u - 1.8 u
= 1.2 u
Number of apples left
= 3 x 1.2 u
= 3.6 u
Number of apples sold
= 11 u - 3.6 u
= 7.4 u
7.4 u = 148
1 u = 148 ÷ 7.4 = 20
Number of persimmons and apples at first
= 3 u + 11 u
= 14 u
= 14 x 20
= 280
Answer(s): 280
