Question

In a school, if there are 36% boys and 352 girls, then the number of boys is

Answer 1

total no of students be x
36%of x + 352=x
36x/100 +352 = x
352= x-36x/100
352 =64x/100
x = 352×100/64 = 35200/64 = 550
if total number of students is 550 and no of girls is 352 then
number of boys = 550-352 = 198
hope this helps

Answer 2

Let the total no. Of children be x.
Then the no. Of boys is=(36/100)x
Ni. Of girls=352
352+(36/100)x=x
352=x-(36/100)x
352=(64/100)x
x=550
No. Boys is =(36/100)*550
=198
