Marks: +1, -0

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?

Validate

Solution:

Suppose the man works overtime for x hours.
Now, regular working hours in 4 weeks

= 5× 8 × 4 = 160

hours
Therefore,

160 × 2.40 + x × 3.20 = 432

3.20x = 432 - 384 = 48

⇒ x = 15
Hence, total hours of work = 160 + 15 = 175
