Let the number of pedicure vouchers be x

⇒ The number of haircut vouchers = 130 + x

⇒ x + 130 + x = 450

⇒ x = 160

⇒ Haircut vouchers = 130 + 160 = 290

Ratio of male and female getting the pedicure voucher = 13 ? 7

⇒ Number of female getting the pedicure voucher = 7/20 × 160 = 56

∴ Required percent = 19%
