Answer  No.3
according to the equation it might be
1x2=2 and same as 1x2=2 therefore 11=22
2x2=4 and same as 3x2=6 therefore 23=46
3x2=6 and same as 4x2=8 therefore 34=68
means each number multiplied by 2
so answer will be
4x2=8 and the same as 6x2=12 therefore 46=812.

 The Math Challenger!!!
       
Well! It's a fun mind game, it should be solve according to                                   DMAS rule.

The above given as B+B=2
means 2B=2
B=2/2
B=1.


B+C=5
C=5-B
i.e, C=5-1
So C=4.

Then asked for
B+Cx2=?
It should be solved by DMAS rule.
So
B+Cx2
i.e, 1+(4x2)
1+8
9.
