In the Hillside summer camp there are 50 children. 90% 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?
Choose the most appropriate option.
A) 50
B) 45.
C) 40.
D) 30.
E) 25.
Given there are 50 students , 90% of 50 = 45 boys and remaining 5 girls.   Now here 90% are Boys and 10% are Girls.   Now question is asking about how many boys do we need to add, to make the girls percentage to 5 or 5%..   If we add 50 to existing 45 then the count will be 95 and the girls number will be 5 as it.   Now boys are 95% and girls are 5%. ( out of 100 students = 95 boys + 5 girls ).   50nswer: option 50 is correct.
