In a regular week, there are 5 working days and for each day, the working hours are 8. A man gets Rs. 2.40 per hour for regular work and Rs. 3.20 per hours for overtime. If he earns Rs. 432 in 4 weeks, then how many hours does he work for ?
Answer: Option
Explanation:
Suppose the man works overtime for x hours.
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
160 x 2.40 + x x 3.20 = 432
3.20x = 432 - 384 = 48
x = 15.
Hence, total hours of work = (160 + 15) = 175.

Amount gathered in 4 weeks ( 5 working day each) = (2.4*8)*5*4 = Rs. 384.
Time did in normal shift = 384/2.4 = 160 hours.
Amount remaining = 432-384 = 48.
Overtime did = 48/3.2 = 15 hours.
Total Time = 160+15 = 175 hours.
Time did in normal shift = 384/2.4 = 160 hours.
Amount remaining = 432-384 = 48.
Overtime did = 48/3.2 = 15 hours.
Total Time = 160+15 = 175 hours.

As @Kachani said it was never mentioned like he worked on all his working hours. Suppose if he was off for one day and worked 16 hours next day (regular 8 hour shift and 8 hours overtime)?

Total days=7
Present days=5
Work hours=5
Regular hours=8hr/day *20 days=160 hours
So 2.40*160=384(so regular hours he worked is 160 hours)
Remaining amount he earned is Rs.48.
So overtime earning per hour is Rs. 3.20
Overtime working hours is Rs.48/3.20= 15 hours.
Total worked hours of a man is 160+15=175 hours.
Present days=5
Work hours=5
Regular hours=8hr/day *20 days=160 hours
So 2.40*160=384(so regular hours he worked is 160 hours)
Remaining amount he earned is Rs.48.
So overtime earning per hour is Rs. 3.20
Overtime working hours is Rs.48/3.20= 15 hours.
Total worked hours of a man is 160+15=175 hours.

But it is never mentioned that the man has worked all his regular working hours right? So how can we assume 160*2.40 ?
