In a box, there are some lemons and pomegranates. If 72 pomegranates are removed from the box, the percentage of pomegranates will increase from 25% to 70%. How many pomegranates are there in the box?

Lemons |
Pomegranates |
Before |
1x7 = 7 u |
3x7 = 21 u |
Change |
No change |
- 72 |
After |
7x1 = 7 u |
3x1 = 3 u |
25% =
25100 =
14 70% =
70100 =
710 The number of lemons remains unchanged at first and in the end. Make the number of lemons the same. LCM of 7 and 1 is 7.
Number of pomegranates removed
= 21 u - 3 u
= 18 u
18 u = 72
1 u = 72 ÷ 18 = 4
Number of pomegranates
= 21 u
= 21 x 4
= 84
Answer(s): 84
