bike is rented for 8 hours or less, the charge is Rs. 100 per hour or Rs. 8 per km, whichever is more. On the other hand, if the bike is rented for more than 8 hours, the charge is Rs. 80 per hour or Rs. 6 per km, whichever is more. Adarsh used the bike for 120 km and paid Rs. 800. Determine the number of hours he took the bike for rent.Solution
ATQ, Let the travel bike is rented for 8 hours or less. Then the number of hours it is rented for 800/100 = 8 hours But if it charged Rs.8/km, the amount that should paid be 120(8) = 960 But he paid only Rs.800 The travel bike is rented for more than 8 hours Number of hours = 800/80 = 10 hours If it is charged at Rs.6/km, the amount that should paid be 120(6) = Rs.720 which is less than s. 800 Adarsh rented bike for 10 hours.
