In a box, there are some mangoes and passion fruits. If 160 passion fruits are removed from the box, the percentage of passion fruits will increase from 30% to 70%. How many passion fruits are there in the box?
|
Mangoes |
Passion fruits |
Before |
3x7 = 21 u |
7x7 = 49 u |
Change |
No change |
- 160 |
After |
7x3 = 21 u |
3x3 = 9 u |
30% =
30100 =
310 70% =
70100 =
710 The number of mangoes remains unchanged at first and in the end. Make the number of mangoes the same. LCM of 7 and 3 is 21.
Number of passion fruits removed
= 49 u - 9 u
= 40 u
40 u = 160
1 u = 160 ÷ 40 = 4
Number of passion fruits
= 49 u
= 49 x 4
= 196
Answer(s): 196
