Question

60% of the students in a school are girls. If the number of boys in the school is 320 the total number of students in the school is

Answer 1

Number of boys = 320
Percentage of girls in the school = 60 %
Parentage of boys in the school
= 100% - 60%
= 40 %
______________________
Let the total number of students in a school be x ;

40% of x = 320
(40/100)×x = 320
x = 3200/4
x = 800
_____________________
Hence the total number of students is 800

Answer 2

Total % of students= 100 %
% of girls = 60 %
% of boys = 100 % - 60% = 40 %

Number of boys = 320

Let the total number of students be X

So, 40% of X = 320
40/100 x X = 320
X = 320 x 100/40
X = 800

Hence, total number of students is 800.
