In a box, there are some apples and pomegranates. If 30 pomegranates are removed from the box, the percentage of pomegranates will increase from 30% to 75%. How many pomegranates are there in the box?

Apples |
Pomegranates |
Before |
3x1 = 3 u |
7x1 = 7 u |
Change |
No change |
- 30 |
After |
3x1 = 3 u |
1x1 = 1 u |
30% =
30100 =
310 75% =
75100 =
34 The number of apples remains unchanged at first and in the end. Make the number of apples the same. LCM of 3 and 3 is 3.
Number of pomegranates removed
= 7 u - 1 u
= 6 u
6 u = 30
1 u = 30 ÷ 6 = 5
Number of pomegranates
= 7 u
= 7 x 5
= 35
Answer(s): 35
