Sunday Times Teaser 2652 – Square Meals
by Robin Nayler
A company uses ingredients numbered 1 to 10 to mix five different types of meusli. Each one has a square number of ingredients and the weight of each ingredient used is the square of the ingredient’s numbet. The total weight of each mixture is a perfect square.
Last month one ingredient had run out so only two types of meusli could be produced. This week only one, different, type of meusli could be made because a different ingredient had run out.
What are the ingredient’s numbers for this week’s meusli?
