Question

The number of boys in school is 120 more than the girls . If there are 980 students in the school, find the number of boys in the school. ( this problem includes algebraic equation to solve)

Answer 1

say number of girls is X
then, number of boys will be X+120
Total number of students is 980
that means
X+120+X=980
2X+120 =980
2X = 980-120
2X = 860
so X= 860/2 = 430
