Question

In a school, the number of boys and the girls is in the ratio of 2:3. If the number of boys is increased by 20% and that of girls is increased by 10%, what will be the new ratio of the
number of boys to that of the girls?​

Answer 1

Step-by-step explanation:

let no of boys be 2x

let no of girls be 3x

their increased no is 120% of 2x and 110% of 3x

(120/100)×2x and (110/100)×3x

(12x/5):(33x/10)

24:33
