Valen had chikoos and kiwis. The ratio of chikoos to kiwis was 7 : 4. After
34 of the chikoos and 105 kiwis were sold, there were 7 times as many chikoos as kiwis left. How many chikoos and kiwis were sold?
| |
Chikoos |
Kiwis |
Comparing chikoos
and kiwis at first |
7x4 =
28 u |
4x4 =
16 u |
| Before |
4x7 =
28 u |
|
| Change |
- 3x7 =
- 21 u |
- 105 |
| After |
1x7 =
7 u |
|
Comparing chikoos
and kiwis in the end |
7 u |
1 u |
The number of chikoos at first is repeated. Make the number of chikoos at first the same. LCM of 7 and 4 is 28.
Number of kiwis sold
= 16 u - 1 u
= 15 u
15 u = 105
1 u = 105 ÷ 15 = 7
Number of chikoos and kiwis sold
= 21 u + 105
= 21 x 7 + 105
= 147 + 105
= 252
Answer(s): 252
