Solution

The correct option is C x(18,14)
We have,
6x4x1<12

Now,
6x4x112<0
12x4x+12(4x1)<0
8x+12(4x1)8x+1(4x1)<0
Above inequality is true iff numerator and denominator have different signs.

Case 1 : 8x+1>0 and 4x1<0
x>18 and x<14
i.e, x(18,14)

Case 2 : 8x+1<0 and 4x1>0
x<18 and x>14

No common region,
Hence, there is no solution for case 2.

So, final result will be, x(18,14)

Hence the correct answer is option (c).
