Mr Sahni employed a worker for a certain work to be done in some days. He pays ₹ 20 to the worker for each working day and the payment is reduced by ₹ 3 for each non-working day of the worker. For how many days the worker does remain absent from work if at the end of 120 days, he gets ₹ 560 as total remuneration?
Explanation
Let the worker remains absent for 'x' days
Then, his working days =(120-x) days
According to the question
= 20(120-x)-3x= 560
= 2400- 20x-3x= 560
= x== 80 days
= x = 80 days.
Hence, Option A is correct.
