Vincent had peaches and oranges. The ratio of peaches to oranges was 3 : 2. After
14 of the peaches and 70 oranges were sold, there were 9 times as many peaches as oranges left. How many peaches and oranges were sold?

Peaches |
Oranges |
Comparing peaches
and oranges at first |
3x4 =
12 u |
2x4 =
8 u |
| Before |
4x3 =
12 u |
|
| Change |
- 1x3 =
- 3 u |
- 70 |
| After |
3x3 =
9 u |
|
Comparing peaches
and oranges in the end |
9 u |
1 u |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 3 and 4 is 12.
Number of oranges sold
= 8 u - 1 u
= 7 u
7 u = 70
1 u = 70 ÷ 7 = 10
Number of peaches and oranges sold
= 3 u + 70
= 3 x 10 + 70
= 30 + 70
= 100
Answer(s): 100
