Answer or Solution : Which Number Will Replace The Question Mark?
1. You can see that when you add the numbers in any row either vertically or horizontally, (except diagonally), you get a total of 15.
2. In the 1st column 9+1+5=15, in the 1st row 9+4+2=15.
3. In the 3rd column 2+6+7=15, in 2nd row 1+8+6=15.
4. Hence, you need to find the number that is needed to add to 8+4 or 5+7 to obtain the number 15.
5. The answer is 3. 8+4+3 = 5+3+7 = 15.
