A fruit seller had persimmons and mangoes. The ratio of persimmons to mangoes was 3 : 10. After
25 of the persimmons and 69 mangoes were sold, there were 3 times as many persimmons as mangoes left. How many persimmons and mangoes were there at first?
| |
Persimmons |
Mangoes |
Total |
| Before |
3 u |
10 u |
13 u |
| Change |
- 1.2 u |
- 69 |
|
| After |
1.8 u |
5.4 u |
|
Number of persimmons sold
=
25 x 3 u
= 1.2 u
Number of persimmons left
= 3 u - 1.2 u
= 1.8 u
Number of mangoes left
= 3 x 1.8 u
= 5.4 u
Number of mangoes sold
= 10 u - 5.4 u
= 4.6 u
4.6 u = 69
1 u = 69 ÷ 4.6 = 15
Number of persimmons and mangoes at first
= 3 u + 10 u
= 13 u
= 13 x 15
= 195
Answer(s): 195
