Answer 2

A square of nine numbers is marked in a calendar. The sum of all these numbers is 90.

Let’s start with looking at a typical calendar

Notice how numbers are typically arranged?

We will use x to represent the middle number of the square. This means that our 9 numbers are:

Adding these, the total is clearly just 9x

From the question, we are told that the sum of the nine numbers is 90, thus:

9x=90⇒x=10

Thus the nine numbers are: 2, 3, 4, 9, 10, 11, 16, 17, 18
