IBPS PO 2018 · Question 50 of 98
Caselet
Let the number of pedicure vouchers be x ⇒ The number of haircut voucher = 130 + x ⇒ x + 130 + x = 450 ⇒ x = 160. Ratio of male and female getting the pedicure voucher = 13 : 7 ⇒ Number of male getting the pedicure voucher = 13/20 × 160 = 104. ⇒ Number of female getting the pedicure voucher = 7/20 × 160 = 56. ∴ Required difference = 104 – 56 = 48.
