A taxi-driver, filled his car petrol tank with 40 liters of petrol on Monday. The next day, he filled the tank with 50 liters of petrol. If the petrol costs Rs.44 per liter, how much did he spend in all on petrol? |

Answer» Petrol filled on Monday = 40 liters Petrol filled on next day = 50 liters Total petrol filled = 90 liters = 44 x (100 – 10) = 44 x 100 – 44 x 10 = 4400 – 440 = Rs.3960 Therefore, he spent Rs.3960 on petrol. |
