Question
Ali the barber shaved 35% of his customers and gave a
haircut to 45% of his customers. He charged Rs. 9 for a shave and Rs. 7 for a haircut. If 20% of customers who opted for a shave also had a hair-cut, what were Ali's earnings if he had 160 customers (in Rs.)?ÂSolution
Total customers = 75 Numbers of customers shaved = 160 x (35/100) = 56 Number of customers who got hair cut = 160 x (45/100) = 72 Number of customers who shaved and got hair cut = 160 × (20/100) = 32 ∴ His total income= (56 x 9) + (72 x 7) + (32 × 16) = 1520
