The schedule working hour of a labour in a week if 48 hours and he gets Rs. 480 for that. Over time rate is 25% more than the the basic salary rate. In a week a labour gets Rs. 605, how many hours altogether he works in that week.

Explanation:-

Schedule working hours in week = 48.
Total pay in a week for schedule working hours = Rs. 480.
Pay per hour for schedule working hours = 480/48 = Rs. 10.
Pay per hour for over time = 10 + 25% of 10 = Rs. 12.5.
Total pay in that particular week = Rs. 605.
Extra pay = 605 - 480 = 125.
So, total over time = 125/12.5 = 10 hours.

Thus, total work hour altogether in that week = 48 +10 = 58 hours.
