Riordan had peaches and apples. The ratio of peaches to apples was 8 : 7. After
45 of the peaches and 340 apples were sold, there were 8 times as many peaches as apples left. How many peaches and apples were sold?
| |
Peaches |
Apples |
Comparing peaches
and apples at first |
8x5 =
40 u |
7x5 =
35 u |
| Before |
5x8 =
40 u |
|
| Change |
- 4x8 =
- 32 u |
- 340 |
| After |
1x8 =
8 u |
|
Comparing peaches
and apples in the end |
8 u |
1 u |
The number of peaches at first is repeated. Make the number of peaches at first the same. LCM of 8 and 5 is 40.
Number of apples sold
= 35 u - 1 u
= 34 u
34 u = 340
1 u = 340 ÷ 34 = 10
Number of peaches and apples sold
= 32 u + 340
= 32 x 10 + 340
= 320 + 340
= 660
Answer(s): 660
