Question

36 % of student in a school are girls if no of boys is 816 find Total Girls in the school

Answer 1

36% are girls
64% are boys
64% of x = 816 [let x be totla mo. Of students]
X=816*100/64=
1275
Total girls = 1275-816=459

Answer 2

Let, the number of total students be X.
percentage of girls =36%
Number of boys =816
percentage of boys =(100-36)%= 64%

According to the question,

64% of X=816
=>64/100 ×X=816
=>16/25 X=816
=>X=816÷16/25
=>X=816×25/16
=1275
Therefore, total number of students =1275

hence,Number of girls =36% of 1275
= 36/100×1275
=459.
