Find the ratio between Total number persons who use their coupons in Pedicure to total number of persons who use their coupons in Haircutting?

Let, Males and females who use their coupons in Haircutting be 13x and 7x respectively. ⇒ Males who use their coupons in Pedicure = 7x+72 Then Females who use their coupons in Pedicure = 450−13x−7x−7x−72=378−27x / ATQ, 7x+72+13x−(7x+378−27x)=174 40x–306=174 40x = 480 X =12 /

Required Ratio = $frac{{156 + 54}}{{156 + 84}} = frac{{210}}{{240}} = frac{7}{8}$
