Question

in a classroom, the number of boys is 3 times the number of girls and the total number of students is 52. what is the number of boys?​

Answer 1

let the number of girls be X . then the number of boys = 3x
According to the question :-
X + 3x = 52
4x = 52
X = 52/4
X = 13
Number of boys = 3x = 3 × 13 = 39

Answer 2

total students=52

let no of girls be x

let no of boys be 3x

x+3x=52

4x=52

x=52/4

=13

girls=x=13

boys=3x =3×13

=39
