In a container, there are some apples and oranges. If 20 oranges are removed from the container, the percentage of oranges will increase from 40% to 80%. How many oranges are there in the container?
|
Apples |
Oranges |
Before |
2x2 = 4 u |
3x2 = 6 u |
Change |
No change |
- 20 |
After |
4x1 = 4 u |
1x1 = 1 u |
40% =
40100 =
25 80% =
80100 =
45 The number of apples remains unchanged at first and in the end. Make the number of apples the same. LCM of 4 and 2 is 4.
Number of oranges removed
= 6 u - 1 u
= 5 u
5 u = 20
1 u = 20 ÷ 5 = 4
Number of oranges
= 6 u
= 6 x 4
= 24
Answer(s): 24
