उत्तर

 Let Rs x be the income for 20 days of work.
 

Income (in Rs) 200 x
Number of days 8 20

\[\text{ Since the income and the number of working days are in direct variation, we have }  \]
\[\frac{200}{x} = \frac{8}{20}\]
\[ \Rightarrow 200 \times 20 = 8x\]
\[ \Rightarrow x = \frac{200 \times 20}{8}\]
\[ = \frac{4000}{8}\]
\[ = 500\]
\[\text{ Thus, the worker will get Rs 500 for working 20 days } .\]
