In the Hillside summer camp there are 50 children. 85% of the children are boys and the rest are girls. The camp administrator decided to make the number of girls only 5% of the total number of children in the camp. How many more boys must she bring to make that happen? Pick:
A) 20.	B) 45.	C) 50.	D) 30.	E) 25.
Given there are 50 students , 84% of 50 = 42 boys and remaining 8 girls.   Now here 84% are Boys and 16% are Girls.   Now question is asking about how many boys do we need to add, to make the girls percentage to 5 or 8%..   If we add 50 to existing 45 then the count will be 92 and the girls number will be 8 as it.   Now boys are 92% and girls are 8%. ( out of 100 students = 92 boys + 8 girls ).   IMO option 50. is correct.
