Warren had chikoos and apples. The ratio of chikoos to apples was 9 : 4. After
34 of the chikoos and 105 apples were sold, there were 9 times as many chikoos as apples left. How many chikoos and apples were there at first?
| |
Chikoos |
Apples |
Comparing chikoos
and apples at first |
9x4 =
36 u |
4x4 =
16 u |
| Before |
4x9 =
36 u |
|
| Change |
- 3x9 =
- 27 u |
- 105 |
| After |
1x9 =
9 u |
|
Comparing chikoos
and apples in the end |
9 u |
1 u |
The number of chikoos at first is repeated. Make the number of chikoos at first the same. LCM of 9 and 4 is 36.
Number of apples sold
= 16 u - 1 u
= 15 u
15 u = 105
1 u = 105 ÷ 15 = 7
Number of chikoos and apples at first
= 36 u + 16 u
= 52 u
= 52 x 7
= 364
Answer(s): 364
