i guess hope it helps

Answer 2

The correct answer could be the option (2) - 10.

If we see the numbers in the grid, they are arranged in a 3 x 3 matrix.

A simple and logical way to solve this puzzle is by summing up the numbers
vertically.

The first column of the numbers adds up to give a total sum of 40 (5 + 15 + 20 = 40).

Similarly, the numbers in the second column also add up to a total of 40 i.e., 25 + 10 + 5 = 40.

By keeping the same logic into consideration for the third column also, we should get the total as 40. Let the unknown number be 'x'.

So, 18 + 12 + x = 40

30 + x = 40.

So, x = 40 - 30 = 10

Therefore, x = 10.
