Vincent had persimmons and mangoes. The ratio of persimmons to mangoes was 5 : 2. After
34 of the persimmons and 42 mangoes were sold, there were 5 times as many persimmons as mangoes left. How many persimmons and mangoes were sold?

Persimmons |
Mangoes |
Comparing persimmons
and mangoes at first |
5x4 =
20 u |
2x4 =
8 u |
| Before |
4x5 =
20 u |
|
| Change |
- 3x5 =
- 15 u |
- 42 |
| After |
1x5 =
5 u |
|
Comparing persimmons
and mangoes in the end |
5 u |
1 u |
The number of persimmons at first is repeated. Make the number of persimmons at first the same. LCM of 5 and 4 is 20.
Number of mangoes sold
= 8 u - 1 u
= 7 u
7 u = 42
1 u = 42 ÷ 7 = 6
Number of persimmons and mangoes sold
= 15 u + 42
= 15 x 6 + 42
= 90 + 42
= 132
Answer(s): 132
