Mifty is a farmer. She wants to sell the wheat cultivated in her farm. One day, a customer comes to Mifty's house and gives her 3 barrels having a capacity to store 5 kg, 15 kg and 25 kg of wheat. The customer puts a condition before her. She will have to sell him exactly 49 kg of wheat by using only these 3 barrels for measurement. How many minimum moves will she require if has unlimited supply of wheat?
Dividing a barrel is not allowed. If she wants to use one barrel, then it should be filled completely. Help Mifty!
