Answer 2

the answer is option 3) 12

there is a reason to choose this answer

we see that a = 10(110)12

here the difference between 12 and 10 is 2

in b= 15(185)13 also we see 15 - 13 is 2

so we can say 14-12 is also 2

and there other reason too.........10× 12 = 120

if we 120-10 then we get 110

15×13 is 195........195-10 is 185

so 12× 14 is 168 ........168-10 = 158

so I think option 3) is correct........I hope it helps you
