In a box, there are some oranges and pomegranates. If 15 pomegranates are removed from the box, the percentage of pomegranates will increase from 40% to 60%. How many pomegranates are there in the box?

Oranges |
Pomegranates |
| Before |
2x3 =
6 u |
3x3 =
9 u |
| Change |
No change |
- 15 |
| After |
3x2 =
6 u |
2x2 =
4 u |
40% =
40100 =
25 60% =
60100 =
35 The number of oranges remains unchanged at first and in the end. Make the number of oranges the same. LCM of 3 and 2 is 6.
Number of pomegranates removed
= 9 u - 4 u
= 5 u
5 u = 15
1 u = 15 ÷ 5 = 3
Number of pomegranates
= 9 u
= 9 x 3
= 27
Answer(s): 27
