Question

Find the value of A + B in the given magic square.

• A. 1
• B. 0
• C. 2
• D. 3

Answer 1

The correct option is C 2

In a magic square, sum of numbers in any row, column, or diagonal is same.

The magic sum of the given square = Sum of numbers in the first column = 3 + 8 + 1 = 12

Also, sum of 2nd column = B + 4 + 6 = 12
Thus, B = 12 - (6 + 4) = 12 - 10 = 2

So, Sum of third column = 12
Thus, value of A = 12 - (7 + 5) = 12 - 12 = 0

Hence, A + B = 0 + 2 = 2
