Suppose you have 27 weights weighing: 1², 2², 3², 4², ........, 25², 26² and 27² grams respectively.

(a)How can you group them into three groups so that each group has the same weight ?

(b) Is it possible to divide it into more than three groups satisfying the same conditions ?

(In reply to re: very easy by Charlie)

The hardest part of the problem for you is reading the directions! And it's obviously not very easy if it's a difficulty of 3/5.
