Answer 2

Step-by-step explanation:

Let x be the number of days for which the worker is paid Rs.1200.

Income ( in Rs ) 480 1200

Number of days 12 x

Since, the income of the worker and the number of working days are in direct variation we have:

480/1200 = 12/x

480 × x = 12 × 1200

x = 12 × 1200 / 480

x = 30

∴ The required number of days is 30.
