In a box, there are some mangosteens and passion fruits. If 50 passion fruits are removed from the box, the percentage of passion fruits will increase from 30% to 80%. How many passion fruits are there in the box?

| Before |
3x4 =
12 u |
7x4 =
28 u |
| Change |
No change |
- 50 |
| After |
4x3 =
12 u |
1x3 =
3 u |
30% =
30100 =
310 80% =
80100 =
45 The number of mangosteens remains unchanged at first and in the end. Make the number of mangosteens the same. LCM of 4 and 3 is 12.
Number of passion fruits removed
= 28 u - 3 u
= 25 u
25 u = 50
1 u = 50 ÷ 25 = 2
Number of passion fruits
= 28 u
= 28 x 2
= 56
Answer(s): 56
