Vedclass · Answer

Let the third number be $x$

Second number $=2 	imes x=2 x$

First number $=2 	imes 2 x=4 x$

Average of reciprocal of numbers $=\frac{1}{3}\left(\frac{1}{x}+\frac{1}{2 x}+\frac{1}{4 x}ight)$

$=\frac{1}{3 x}\left(\frac{4+2+1}{4}ight)=\frac{7}{12 x}=\frac{7}{72}$

$x=6$

Numbers are $6,12,24$

Of the three numbers, the first is twice the second and the second is twice the third. The average of the reciprocal of the numbers is $\frac{7}{72} .$ The numbers are
