Question

User A bag of 10kg potatoes lasts for a week with a family of 7 people . Assuming all eat the same amount. How long will the potatoes last if there are only two in the family ?

Answer 1

3.5 weeks or 24.5 days

Explanation:

First, we need to find out how many kg each person consumes in one week.
In order to do this, we can;

10/7 = 1.43 kg

Next, we can find out how many kg would be consumed by two people.

1.43 * 2 = 2.86 kg

Finally, we can divide 10 kg of potatoes we have by the 2.86 kg of weekly consumption to get how many weeks it'll last.

10/2.86 = 3.4965 or 3.5 weeks
3.5 * 7 = 24.5 days
