At a fruit stall, there were 572 chikoos and starfruits at first.
14 of the chikoos and
18 of the starfruits were sold. In the end, there were same number of chikoos and starfruits. How many more chikoos than starfruits were sold?
|
Chikoos |
Starfruits |
Before |
4x7 = 28 u |
8x3 = 24 u |
Change |
- 1x7 = - 7 u
|
- 1x3 = - 3 u
|
After |
3x7 = 21 u |
7x3 = 21 u |
Comparing chikoos and starfruits in the end |
1x21 = 21 u |
1x21 = 21 u |
The number of chikoos and starfruits in the end is the same. Make the number of chikoos and starfruits in the end the same. LCM of 3, 7 and 1 is 21.
Number of chikoos and starfruits in the end
= 28 u + 24 u
= 52 u
52 u = 572
1 u = 572 ÷ 52 = 11
Number of more chikoos than starfruits sold
= 7 u - 3 u
= 4 u
= 4 x 11
= 44
Answer(s): 44
