What is the third proportional to $4$ and $12$? / $4$ और $12$ का तृतीय समानुपाती क्या है?
1.
$36$ / $36$
2.
$24$ / $24$
3.
$48$ / $48$
4.
$32$ / $32$
Correct Answer: $36$ / $36$
If the third proportional is $x$, then $\frac{4}{12} = \frac{12}{x} \Rightarrow x = 36$. The trap is to take the mean proportional ($\sqrt{48}$) instead. / यदि तृतीय समानुपाती $x$ हो, तो $\frac{4}{12} = \frac{12}{x} \Rightarrow x = 36$। भ्रम मध्य समानुपाती ($\sqrt{48}$) लेना है।
