In a tuckshop,
57 of the children wore caps. After 444 children who wore caps left the tuckshop, the percentage of children who wore caps decreased to 45%. How many children in the tuckshop did not wear caps?
|
Wore caps |
Did not wear caps |
Before |
5x11 = 55 u |
2x11 = 22 u |
Change |
- 444 |
|
After |
9x2 = 18 u |
11x2 = 22 u |
45% =
45100 =
920The number of children who did not wear caps remains unchanged. LCM of 2 and 11 is 22.
Number of children who wore caps and left
= 55 u - 18 u
= 37 u
37 u = 444
1 u = 444 ÷ 37 = 12
Number of children who did not wear caps
= 22 u
= 22 x 12
= 264
Answer(s): 264
