Question

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 1

 the man works overtime for x hours.

∴ 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.

∴ total hours of work = (160 + 15) 

                                 = 175.
