In a container, there are some apples and mangosteens. If 28 more mangosteens are put into the container, the percentage of apples will decrease from 60% to 25%. How many apples are there in the container?

Apples |
Mangosteens |
Before |
3x1 = 3 u |
2x1 = 2 u |
Change |
No change |
+ 28 |
After |
1x3 = 3 u |
3x3 = 9 u |
60% =
60100 =
35 25% =
25100 =
14 The number of apples remains unchanged at first and in the end. Make the number of apples the same. LCM of 3 and 1 is 3.
Number of mangosteens added
= 9 u - 2 u
= 7 u
7 u = 28
1 u = 28 ÷ 7 = 4
Number of apples
= 3 u
= 3 x 4
= 12
Answer(s): 12
