Question

Complete the magic square given below. [5 Marks]

11		7
	8
4		5

Answer 1

From the right diagonal,
Magic sum = 11 + 8 + 5 = 24 [1 Mark]
In the first row,
missing term = 24 - (11 + 7) = 24 - 18 = 6 [1 Mark]
In the first column,
missing term = 24 - (11 + 9) = 24 - 20 = 4 [1 Mark]
In the second column,
missing term = 24 - (6 + 8) = 24 - 14 = 10 [1 Mark]
In the second row,
missing term = 24 - (4 + 8) = 24 - 12 = 12 [1 Mark]
The completed magic square:

11	6	7
4	8	12
9	10	5
