Question

a employee works in a company on a contract of 30 days on the condition that he will receive to rupees 200 for each day he works and he will be fined Rs 20 each day he is absent if you received Rs 3800 in all for how many days did he remain absent

Answer 1

Answer:

Let x be number of days absent.

30−x is number of days worked.

He gets 200rs when he works.

He gets - 20rs when he does not work (fine)

200(30−x)+−20x=3800

6000−200x−20x=3800

−220x=3800−6000=−2200 x=2200220=10

So he was absent for 10 days.
