If $\displaystyle \mathrm{n}_1, \mathrm{n}_2$ and $\displaystyle \mathrm{n}_3$ are the fundamental frequencies of three segments into which a string is divided, then the original fundamental frequency n of the string is given by :
Official answer
From NTA’s final answer key for this paper.
(1)
$\displaystyle \frac{1}{\mathrm{n}}=\frac{1}{\mathrm{n}_1}+\frac{1}{\mathrm{n}_2}+\frac{1}{\mathrm{n}_3}$
