Question

If the sum of the numbers in each row and column is same, which number can best replace the question mark in the figure?

Answer 1

Sum of the numbers in the second row = 29 + 25 + 21
= 75
So, the sum of the numbers in the first row will also be 75
Missing number + 24 + 23 = 75
Missing number = 75 - 47
= 28
The sum of numbers in the third column will also 75.
Missing number + 28 + 21 = 75
Missing number = 75 - 49
= 26
So, '26' can replace the question mark in the figure.
