1 2 7
2 14 X
3 105 117
Solution:-
step 1) By considering first column
1×2=2
Add first column first number
to that ..then that is 2 +1 =3 ..
First operation is completed.
Step 2)By considering second column
7×14= 98
Add second column first
number to that ..then that is
98 + 7 = 105.
Second operation is completed.
Step 3) missing number is
considered as X variable ..
Then (9X)+9 =27 solve this equation ..
That is 9X = 108
X = 12
Therefore ans is 12 😁
