The grid of numbers with a row and column sum of 30 is

3   15  12

17   11   2

10  4   16

<h3>How to prepare the grid?</h3>

The grid in the question has a row sum and column sum of 15

The question implies that we create a similar grid with a row sum and column sum of 30

Represent the grid as follows:

a    b   c

d    e    f

g   h    j

So, we have the following sum of rows

a + b + c = 30

d + e + f = 30

g + h + j = 30

And, we have the following sum of rows

a + d + g = 30

b + e + h = 30

c + f + j = 30

Using trial by error, we have:

3 + 15+ 12  = 30

17 + 11 + 2 = 30

10 + 4 + 16 = 30

When the columns are added, we have

3 + 17 + 10 = 30

15 + 11 + 4 = 30

12 + 2 + 16 = 30

Hence, the grid of numbers is

3   15  12

17   11   2

10  4   16
