Correct Answer:

Explanation:

Let, the 2nd number = x

1st number will be $\frac{x}{2}$

And 3rd number will be $\frac{x}{3}$

According to question

=> $\frac{\frac{x}{2}+x+\frac{x}{3}}{3}$ = 44

=> $\frac{x}{2}+x+\frac{x}{3}$ = 44$\times$3

=> $\frac{3x+6x+2x}{6}$ = 132

=> 11x = 132$\times$6

=> x = $\frac{132\times 6}{11}$

x=72
