A housewife has sufficient charcoal to last 12 days provided. She only uses 2 buckets of charcoal a day. How long will the charcoal last if she uses 3 buckets a day?

Alright, here is how you do this.

We know that if the housewife uses 2 buckets a day during the course of 12 days, that means, all in all, she used 6 buckets during those twelve days.

This means that if she uses 3 buckets a day, she will only have enough charcoal for 2 days, because 6/3 is 2.

Therefore, your final answer is 2 days

I hope this helped! Comment if you need me to explain it further or have any questions regarding it! :)

If the housewife uses 2 buckets of coal a day for twelve days, in the course of twelve days she uses 24 buckets of charcoal.

2 x 12 = 24
24/2 = 12

If she uses 3 buckets every day when she was 24 buckets in total, then she would have enough charcoal to go 8 days.

24/3 = 8
