Question

- In a school 65% of the stu-
dents are girls. If the number
of boys is 420, then what is
the total number of students
in the school?​

Answer 1

let the total number of students be x

% of girls = 65%

therefore , the percentage of boys will be 100-65 = 35%

Given , 35% of x = 420

35x/100 = 420

x = 420 × 100/35

= 1200

therefore , the total number of students is 1200.
