Hi friend,
_____________________
In the first column, 2 x 1 + 1 = 3.
In the second column, 14 x 7 + 7 = 105.
Let the missing number in the third column be y.
Then, y x 9 + 9 = 117
or,

Answer 2

Answer:

The answer is d) 12

Step-by-step explanation:

firstly from the question,

                                let us understand , the pattern it holds in the first two columns.

        1      7      9

        2     14     ?

        3    105    117

 the pattern followed here is ,

     1 + ( 1 × 2 ) = 3

     7 + ( 7 × 14 ) = 105

and now to find the final answer ,

            let us take the unknown  value as X

         9 + ( 9 × X ) = 117

       by solving the equation,

             9 × X = 117 - 9

                   X = 108 / 9

                   X = 12

∴ the answer is d) 12
