a man was engaged on a job for 30 days on the condition that he would get a salary of rs. 100 for the day he works, but he has to pay a fine of rs. 80 for each day of his absence. if he gets rs. 2,100 at the end, how many days was he absent for?

**Answer:** Let’s assume the man was absent for ‘x’ days.

Since he worked for 30 days, he was absent for (30 - x) days.

Given that he received Rs. 100 for each day he worked and had to pay a fine of Rs. 80 for each day he was absent, we can set up the following equation:

100(30-x) - 80x = 2100

Simplifying the equation, we get:

3000 - 100x - 80x = 2100

180x = 900

**x = 5**

Since the number of days absent must be a whole number, we round up to get:

x = **5**

Therefore, the man was absent for **5** days.
