Question

6.
A drum of capacity 18litre 500 ml now has 12litre 600 ml of oil. Due to a leak at the bottom
100 ml of oil is lost every hour. How many hours will it take to make the oil in drum
reduce to 10litre?​

Answer 1

100 hours is the answer

Answer 2

The necessary time is 26 hours.

Given data :

Initial volume = 12 litre 600 ml = (12000 ml + 600 ml ) = 12600 ml

Reduced volume = 10 litres = 10000 ml

Loss amount of oil's volume = (12600-10000)ml = 2600ml

100 ml lost in = 1 hour

1 ml lost in = 1/100 hour

2600 ml lost in = 2600/100 = 26 hour (answer)
