Lester has 40 kilograms of wheat. He has a simple balance and 4 weights of whole number denominations. The 4 weights are such that he is able to measure any whole number amount of wheat from 1 to 40 (no fractions). He can use a combination of two or more weights on any side of the balance as required. He can also use one weight on the left side and two or more weights on the right along with the wheat to weigh the required amount if necessary. What are the 4 weights Lester has?
