Answer 2

Answer: $\dfrac{3}{10}$ part of his salary he saved.

Step-by-step explanation:

Since we have given that

Fraction of his salary spend on rent = $\dfrac{1}{5}$

Fraction of his salary spend on food = $\dfrac{1}{3}$

Fraction of his salary spend on clothes = $\dfrac{1}{6}$

Total part of fraction of his salary spent is given by

$\dfrac{1}{5}+\dfrac{1}{3}+\dfrac{1}{6}\\\\=\dfrac{6+10+5}{30}\\\\=\dfrac{21}{30}\\\\=\dfrac{7}{10}$

So, Fraction of his salary he saved is given by

$1-\dfrac{7}{10}\\\\=\dfrac{10-7}{10}\\\\=\dfrac{3}{10}$

Hence, $\dfrac{3}{10}$ part of his salary he saved.
