At a fruit stall, there were 774 mangosteens and kiwis at first.
25 of the mangosteens and
16 of the kiwis were sold. In the end, there were same number of mangosteens and kiwis. How many more mangosteens than kiwis were sold?
|
Mangosteens |
Kiwis |
Before |
5x5 = 25 u |
6x3 = 18 u |
Change |
- 2x5 = - 10 u
|
- 1x3 = - 3 u
|
After |
3x5 = 15 u |
5x3 = 15 u |
Comparing mangosteens and kiwis in the end |
1x15 = 15 u |
1x15 = 15 u |
The number of mangosteens and kiwis in the end is the same. Make the number of mangosteens and kiwis in the end the same. LCM of 3, 5 and 1 is 15.
Number of mangosteens and kiwis in the end
= 25 u + 18 u
= 43 u
43 u = 774
1 u = 774 ÷ 43 = 18
Number of more mangosteens than kiwis sold
= 10 u - 3 u
= 7 u
= 7 x 18
= 126
Answer(s): 126
