At a fruit stall, there were 649 kiwis and chikoos at first.
25 of the kiwis and
18 of the chikoos were sold. In the end, there were same number of kiwis and chikoos. How many less chikoos than kiwis were sold?
|
Kiwis |
Chikoos |
Before |
5x7 = 35 u |
8x3 = 24 u |
Change |
- 2x7 = - 14 u
|
- 1x3 = - 3 u
|
After |
3x7 = 21 u |
7x3 = 21 u |
Comparing kiwis and chikoos in the end |
1x21 = 21 u |
1x21 = 21 u |
The number of kiwis and chikoos in the end is the same. Make the number of kiwis and chikoos in the end the same. LCM of 3, 7 and 1 is 21.
Number of kiwis and chikoos in the end
= 35 u + 24 u
= 59 u
59 u = 649
1 u = 649 ÷ 59 = 11
Number of less chikoos than kiwis were sold
= 14 u - 3 u
= 11 u
= 11 x 11
= 121
Answer(s): 121
