In a box, there are some apples and passion fruits. If 100 passion fruits are removed from the box, the percentage of passion fruits will increase from 20% to 70%. How many passion fruits are there in the box?

Passion fruits |
| Before |
1x7 =
7 u |
4x7 =
28 u |
| Change |
No change |
- 100 |
| After |
7x1 =
7 u |
3x1 =
3 u |
20% =
20100 =
15 70% =
70100 =
710 The number of apples remains unchanged at first and in the end. Make the number of apples the same. LCM of 7 and 1 is 7.
Number of passion fruits removed
= 28 u - 3 u
= 25 u
25 u = 100
1 u = 100 ÷ 25 = 4
Number of passion fruits
= 28 u
= 28 x 4
= 112
Answer(s): 112
