Answer:

let \: the \: denominator \:be \: y \\ numerator \: be \: x\\  \\ according \: to \: question \\   \\  \frac{x + 1}{y} =  \frac{1}{2}   ....(1) \\  \\

 \frac{x - 2}{y}  =  \frac{1}{3} .....(2) \\

solve \: this \: eq

from \: eq \: 1 \\ y = 2x + 2 \\ put \: the \: value \: of \: y \: in \: eq2 \\

 \frac{x - 2}{2x + 2}  =  \frac{1}{3} \\  3x - 6 = 2x + 2 \\ x = 8 \\ y = 2x + 2 \\ y = 18
