In a container, there are some pomegranates and mangosteens. If 25 more mangosteens are put into the container, the percentage of pomegranates will decrease from 60% to 30%. How many pomegranates are there in the container?

Pomegranates |
Mangosteens |
Before |
3x1 = 3 u |
2x1 = 2 u |
Change |
No change |
+ 25 |
After |
3x1 = 3 u |
7x1 = 7 u |
60% =
60100 =
35 30% =
30100 =
310 The number of pomegranates remains unchanged at first and in the end. Make the number of pomegranates the same. LCM of 3 and 3 is 3.
Number of mangosteens added
= 7 u - 2 u
= 5 u
5 u = 25
1 u = 25 ÷ 5 = 5
Number of pomegranates
= 3 u
= 3 x 5
= 15
Answer(s): 15
