A farmer needs 8 gallons of water. He has only three unmarked buckets, two 6 gallon and one 11 gallon bucket.

How can he collect 8 gallons of water using three unmarked buckets? Provide solution with minimal water wastage.

first the farmer should fill the eleven gallon bucket till it's full. then empty that out into one of the six gallon buckets till that one is full. there will be five gallons left in the eleven gallon bucket. so then, you would pour out the water from the six gallon bucket into the other six gallon bucket until it is half full. then the five gallons in the eleven gallon bucket plus one of the half full six gallon buckets equals six, assuming that you discard the water from one of the six gallon buckets.
