Question
Ali the barber shaved 38% of his customers and gave a
haircut to 76% of his customers. He charged Rs. 12 for a shave and Rs. 9 for a haircut. If 25% of customers who opted for a shave also had a hair-cut, what were Ali's earnings if he had 130 customers (in Rs.)?Solution
Total customers = 130 Numbers of customers shaved = 130 x (38/100) = 49.4 Number of customers who got hair cut = 130 x (76/100) = 98.8 ∴ His total income= (49.4 x 12) + (98.8 x 9) = 1482
