Question : 37

Total: 40

E+G

Solution:

Concept:

A magic square has the same sum for every row, column, and main diagonal.

Explanation:

First row sum:

13 + 12 + 17 = 42

So the magic sum for the square is

42

Using the first column:

13 + E + 11 = 42

This gives

E + 24 = 42

, so

E = 18

Using the third column:

17 + 10 + G = 42

This gives

G + 27 = 42

, so

G = 15

Therefore,

E + G = 18 + 15 = 33

Answer:

E + G = 33

, so the correct option is C.
