Here is your answer.

As we know the formula,

Average = $\frac{sum \: of \: observations}{no. \: of \: observations}$

$= \frac{( \frac{1}{5} + \frac{1}{15} + \frac{1}{10}) }{3} \\ \\ = \frac{( \frac{6 + 2 + 3}{30}) }{3} \\ \\ = \frac{11}{30} \times \frac{1}{3} \\ \\ = \frac{11}{90}$

$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope \: it \: helps\: you}}}}}}}}}}}}}}}$

$\huge\boxed{\texttt{\fcolorbox{Red}{yellow}{Be brainly!!}}}$
