Question

The average of Four numbers is $24.5$. Of the four numbers, the first is $1.5$ times the second, the second is $\frac{1}{3}$rd of the third, and the third is $2$ times the fourth number. Then what is smallest of all those numbers?

Answer 1

First number$=1.5x$

Second $=x$

Third$=3x$

Fourth $=1.5x$

Average $=24.5=\frac{(1.5x+x+3x+1.5x)}{4}$

$\Rightarrow 24.5=\frac{7x}{4}$

$\Rightarrow x=\frac{24.5\times 4}{7}=14$

Therefore the number is $14$
