Question

$\begin{array}{ccc}24& 29& 22\\ 27& 25& \\ 28& 21& 26\end{array}$

The missing number in the $3\times 3$ magic square is .

• A. 24
• B. 23
• C. 25

Answer 1

The correct option is B 23

The sum of numbers in any row or column or diagonal of the magic square is the same.

The sum of numbers in 1st row = 24 + 29 + 22 = 75.
It is same for all rows, columns and diagonals.

So in 2nd row, 27 + 25 is 52, the missing number is $75-52=23$.
