Let the person did not work for x days. It means that he worked for (50 - x) days.

∴ Fine for being absent = Rs. 6x

Wages for working days = Rs 12 (50 - x)

Now, according to the question,

Received wages = Rs 12 (50 - x) – 6x = Rs 420

⇒ 600 – 12x – 6x = 420

⇒ 18x = 600 – 420 = 180

$(\therefore x = \frac{{180}}{{18}} = 10\ days)$

Hence, the required number of days is 10.
