10 cans of 5 litre, 20 cans of 3 litre, 15 cans of 2 litre can be filled from oil drum of 200 litre. How many cans of 1 litre can be filled from remaining amount of oil. |

Answer» Amount of oil in drum = 200 litre Total amount of oil filled in 10 cans of 5 litre = 50 litre Total amount of oil filled in 20 cans of 3 litre = 60 litre Total amount of oil filled in 15 cans of 2 litre = 30 litre Therefore, total amount of oil filled = 50 litre + 60 litre + 30 litre = 140 litre Remaining oil = 200 litre – 140 litre = 60 litre Remaining oil can be filled in cans of 1 litre Therefore, number of cans filled in 60 litre oil = 60 |
