It was Mammu’s birthday and I decided to buy for her some
sweets. There was an old woman in the candy shop. I noticed something very
strange, while she was weighing out the sweets. She had just six weights and a
balance scale. That’s all she had. With just this she was able to weigh any
unit number of ounces of candy – right from 1 to 364.
Can you say what the six weights were?
Answer: 1, 3, 9,
27, 81, and 243. All powers of three.
