Could any of the Maths Gurus here kindly help me on this P3 question?


A large container with a capacity of 20 litres is used to contain honey. Each day, a worker will pour in 5 litre of honey but a thief will steal 2 litre of honey. On which day will the large container be filled?

My son’s answer is day 7, but the answer sheet shows day 6.

Would be greatful for any kind explaination to this question. Thanks

Hi,

The answer is 6 days because on the 6th day when the worker pours in the 5 litres, the container is already filled before 2 litres get stolen.

Hi mama_10


Good Morning.

As usual, I've shown more MD than necessary to show the flow of events.

Hope this helps.

Best wishes.
