An employer pays Rs. 30 for each day a worker works, and forfeits Rs. 5 for each day he is idle. At the end of 60 days, a worker gets Rs. 500. For how many days did the worker remain idle?
Choose the correct choice from the following choices:
A) 52 B) 27 C) 99 D) 61 E) 11
Explanation:   Suppose the worker remained idle for m days. Then, he worked for (60 - m) days.   30 (60 - m) – 5m = 500   1800 – 25m = 500   25m = 1300   m = 52   So, the worker remained idle for 52 days.   52NSWER: 52
