Question

In the given magic square, the magic sum is three times of ______.

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Here, the numbers in magic square are
4, 9, 2, 3, 5, 7, 8, 1, 6.

Arranging in ascending order,
1, 2, 3, 4, 5, 6, 7, 8, 9,

The magic sum of the $3\times 3$ magic square is always the number present in the middle of the arranged numbers multiplied by 3.

Here, the middle number in the arrangement 1, 2, 3, 4, $\underset{–}{5}$, 6, 7, 8, 9 is 5.

$\therefore$ Magic sum $=5\times 3=15$.

Thus in the given magic square, the magic sum is three times of 5.
