The company pays salaries to its employees as follows,

Trained employee - Rs.40/ hour

Untrained employee - Rs.30 / hour

Normal working day: 8 hours (if an employee work less than 8 hours in a normal working day, one hour is deducted from his worked hours on that day)

Ex: on the 5th day Nihal has worked only 4 hours, so he's getting salary for 3 hours

Payment for overtime:an hour of over time is considered as 1 1/2 hours.

Ex : Nihal - 18 hours ( 12 hours* 1.5)
