Question

9. The number of boys in a school is 120 more than the numbers of girls. If there are 980 students in the school, find the number of boys and girls in the school.

Answer 1

Step-by-step explanation:

Let,

No. of girls = x

No. of boys = 120 + x

=> 120 + x + x = 980

=> 120 + 2x = 980

=> 2x = 980 - 120

=> 2x = 860

=> x = 860/2

=> x = 430

=> 120 + x = 120 + 430 = 550

Hence,

No. of girls = 430

No. of boys = 550
