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?  Choose the correct option:	A) 160	B) 175	C) 180	D) 195	E) 185
Suppose the man works overtime for x hours.   Now, working hours in 4 weeks = (5 x 8 x 4) = 160.   Therefore, 160 x 2.40 + x x 3.20 = 432   &lt;=&gt; 3.20x = 432 - 384=
