The ratio of kiwis to pomegranates is 3 : 5. If 110 pomegranates are added, the ratio of kiwis to pomegranates will be 1 : 5. How many kiwis are there?
|
Kiwis |
Pomegranates |
Before |
3x1 = 3 u |
5x1 = 5 u |
Change |
|
+ 110 |
After |
1x3 = 3 u |
5x3 = 15 u |
The number of kiwis at first and in the end remains unchanged. Make the number of kiwis at first and in the end the same. LCM of 3 and 1 is 3.
Number of pomegranates added
= 15 u - 5 u
= 10 u
10 u = 110
1 u = 110 ÷ 10 = 11
Number of kiwis
= 3 u
= 3 x 11
= 33
Answer(s): 33
