Question

Find the sum of all coloured blocks in the given magic square.
(3 marks)

Answer 1

First we have to find the sum of the given magic square that will be

26+21+28=75
(0.5 Marks)

Now,

22 + yellow block + 24 = 75

So, yellow block = 29
(0.5 Marks)


21 + Red block + 29 = 75
So, red block = 25
(0.5 Marks)

28 + green block + 24 = 75
So, green block = 23
(0.5 Marks)
Now, the sum of all coloured block will be
29 + 25 + 23 = 77
