Ahmad had mangosteens and kiwis. The ratio of mangosteens to kiwis was 5 : 2. After
12 of the mangosteens and 15 kiwis were sold, there were 5 times as many mangosteens as kiwis left. How many mangosteens and kiwis were sold?
| |
Mangosteens |
Kiwis |
Comparing mangosteens
and kiwis at first |
5x2 =
10 u |
2x2 =
4 u |
| Before |
2x5 =
10 u |
|
| Change |
- 1x5 =
- 5 u |
- 15 |
| After |
1x5 =
5 u |
|
Comparing mangosteens
and kiwis in the end |
5 u |
1 u |
The number of mangosteens at first is repeated. Make the number of mangosteens at first the same. LCM of 5 and 2 is 10.
Number of kiwis sold
= 4 u - 1 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of mangosteens and kiwis sold
= 5 u + 15
= 5 x 5 + 15
= 25 + 15
= 40
Answer(s): 40
