In a box, there are some mangosteens and pomegranates. If 14 pomegranates are removed from the box, the percentage of pomegranates will increase from 40% to 75%. How many pomegranates are there in the box?
|
Mangosteens |
Pomegranates |
Before |
2x3 = 6 u |
3x3 = 9 u |
Change |
No change |
- 14 |
After |
3x2 = 6 u |
1x2 = 2 u |
40% =
40100 =
25 75% =
75100 =
34 The number of mangosteens remains unchanged at first and in the end. Make the number of mangosteens the same. LCM of 3 and 2 is 6.
Number of pomegranates removed
= 9 u - 2 u
= 7 u
7 u = 14
1 u = 14 ÷ 7 = 2
Number of pomegranates
= 9 u
= 9 x 2
= 18
Answer(s): 18
