In a box, there are some chikoos and passion fruits. If 33 more passion fruits are put into the box, the percentage of chikoos will decrease from 80% to 25%. How many chikoos are there in the box?

Chikoos |
Passion fruits |
Before |
4x1 = 4 u |
1x1 = 1 u |
Change |
No change |
+ 33 |
After |
1x4 = 4 u |
3x4 = 12 u |
80% =
80100 =
45 25% =
25100 =
14 The number of chikoos remains unchanged at first and in the end. Make the number of chikoos the same. LCM of 4 and 1 is 4.
Number of passion fruits added
= 12 u - 1 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Number of chikoos
= 4 u
= 4 x 3
= 12
Answer(s): 12
