Question

At the middle school, the number of boys to girls is 7:9. If there are 34 more girls than boys, how many boys and girls are there

Answer 1

boys=119, girls= 153

let the number of boys and girls be 7x and 9x respectively

Then, ATQ

9x=7x+34

therefore, the number of boys is 17×7=119

and number of girls is 17×9=153
