In a box, there are some mangoes and chikoos. If 33 chikoos are removed from the box, the percentage of chikoos will increase from 20% to 75%. How many chikoos are there in the box?
|
Mangoes |
Chikoos |
Before |
1x3 = 3 u |
4x3 = 12 u |
Change |
No change |
- 33 |
After |
3x1 = 3 u |
1x1 = 1 u |
20% =
20100 =
15 75% =
75100 =
34 The number of mangoes remains unchanged at first and in the end. Make the number of mangoes the same. LCM of 3 and 1 is 3.
Number of chikoos removed
= 12 u - 1 u
= 11 u
11 u = 33
1 u = 33 ÷ 11 = 3
Number of chikoos
= 12 u
= 12 x 3
= 36
Answer(s): 36
