In a regular week, there are 5 working days and for each day, the working hours are A man gets Tk. 40 per hour for regular work and Tk. 20 per hours for overtime. If he earns Tk. 432 in 4 weeks, then how many hours does he work for?
Solution
Correct Answer: Option B
Suppose the man works overtime for x hours
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
So, 160 x 2.40 + x x 3.20 = 432
=> 3.20x = 432 - 384 = 48
=>x = 15.
Hence, total hours of work = (160 + 15)
= 175.
