A fruit seller had passion fruits and persimmons. The ratio of passion fruits to persimmons was 3 : 10. After

Passion Fruits |
Persimmons |
Total |
| Before |
3 u |
10 u |
13 u |
| Change |
- 1.2 u |
- 128 |
|
| After |
1.8 u |
3.6 u |
|
Number of passion fruits sold
=
25 x 3 u
= 1.2 u
Number of passion fruits left
= 3 u - 1.2 u
= 1.8 u
Number of persimmons left
= 2 x 1.8 u
= 3.6 u
Number of persimmons sold
= 10 u - 3.6 u
= 6.4 u
6.4 u = 128
1 u = 128 ÷ 6.4 = 20
Number of passion fruits and persimmons at first
= 3 u + 10 u
= 13 u
= 13 x 20
= 260
Answer(s): 260
