Question

(6) In a calendar a square of '9' numbers is
marked. The sum of the numbers is 126
What are
the numbers.
​

Answer 1

Answer:

We will use x to represent the middle number of the square.

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

Hope it helps
