Question

In a school, number of girls is 70 more than the number of boys. If total number of students is 3450 then what will be the number of girls and boys?

Answer 1

1760 girls

1690 boys

Explanation:

let g = number of girls and b = number of boys

g = b + 70

g + b = 3450

substitute b + 70 to g

b + 70 + b = 3450

2b = 3380

b = 1690

to get the number of girls,

use g = b + 70

g = 1690 + 70

g = 1760
