A daily wage worker was paid Rs. 1,700 during a period of 30 days. During this period he was absent for 4 days and was fined Rs. 15 per day for absence. He was paid the full salary only for 18 days as he came late on the other days. Those who came late were given only half the salary for that day. What was the total salary paid per month to a worker who came on time every day and was never absent?

Let salary for full day = Rs. $$2x$$, half day salary = Rs. $$x$$ and absent penalty = Rs. $$15$$

The worker was absent for 4 days, fully paid for 18 days, => He was late for 8 days

According to ques,

=> $$(18\times2x)+(8\times x)-(4\times15)=1700$$

=> $$36x+8x-60=1700$$

=> $$x=\frac{1760}{44}=40$$

$$\therefore$$ Salary paid to the worker who came on time every day and was never absent = $$30\times2\times40=Rs.$$ $$2400$$

=> Ans - (A)
