In a box, there are some apples and pomegranates. If 66 pomegranates are removed from the box, the percentage of pomegranates will increase from 25% to 80%. How many pomegranates are there in the box?
|
Apples |
Pomegranates |
Before |
1x4 = 4 u |
3x4 = 12 u |
Change |
No change |
- 66 |
After |
4x1 = 4 u |
1x1 = 1 u |
25% =
25100 =
14 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 1 is 4.
Number of pomegranates removed
= 12 u - 1 u
= 11 u
11 u = 66
1 u = 66 ÷ 11 = 6
Number of pomegranates
= 12 u
= 12 x 6
= 72
Answer(s): 72
