I think 90 is answer.

Answer 2

Heya user
Here is your answer !!

If you see vertically ,
you will notice that ....

In the 1st column ,
( 9 - 1 ) * 9
= 8 * 9
= 72 .

In the 2nd column ,
( 8 - 1 ) * 7
= 7 * 7
= 49

So , in the third column too , the same rule will be followed .
Hence , the missing number is
( 11 - 1 ) * 9
= 10 * 9
= 90 ..... [Ans]

Hope it helps !!
