In a container, there are some kiwis and oranges. If 28 oranges are removed from the container, the percentage of oranges will increase from 25% to 60%. How many oranges are there in the container?
|
Kiwis |
Oranges |
Before |
1x3 = 3 u |
3x3 = 9 u |
Change |
No change |
- 28 |
After |
3x1 = 3 u |
2x1 = 2 u |
25% =
25100 =
14 60% =
60100 =
35 The number of kiwis remains unchanged at first and in the end. Make the number of kiwis the same. LCM of 3 and 1 is 3.
Number of oranges removed
= 9 u - 2 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of oranges
= 9 u
= 9 x 4
= 36
Answer(s): 36
