savings?​

Answer 1

Answer:

Rohit spends 2/3rd of his salary on rations, 1/5th of it on transport and 1/10th of it on rent. The part of his salary does he spend in all -

$\\ = \frac{2}{3} + \frac{1}{5} + \frac{1}{10} \\ \\ = \frac{20 + 6 + 3}{30} \\ \\ = \frac{29}{30}$

The part of his salary is left as savings -

$= 1 - \frac{29}{30} = \frac{1}{30}$
