Question

the number of boys in school is 120 more than the number of girls if there are 980 student in the school find the number of boys in the school

Answer 1

Let the number of girls be x

Therefore number of boys= x+120

Total number of students= 980.

Number of boys+number of girls= number of students.

(x+120)+x= 980.

2x+120= 980

2x= 980-120

2x= 860

x= 860/2

x= 430

The number of girls is 430.

The number of boys is 430+120= 550.
