Question
‘X’, ‘Y’ and ‘Z’ rented a taxi for a trip. The taxi driver
charges a fixed amount per kilometer. If ‘X’, ‘Y’ and ‘Z’ travelled for 12 km, 15 km and 13 km, respectively and together paid Rs. 2400 to the driver, then find the amount paid by ‘Y’ to the driver.Solution
Let the driver charged Rs. ‘x’ per kilometer. Therefore, amount paid by ‘X’, ‘Y’ and ‘Z’ is Rs. 12x, Rs. 15x and Rs. 13x, respectively So, 12x + 15x + 13x = 2400 Or, 40x = 2400 So, x = 60 Amount paid by ‘Y’ = 15x = 15 × 60 = Rs. 900
