In a typical week, there are five working days with an average of eight working hours each day. For normal labour, a man is paid Rs. 2.40 per hour, and for overtime, he is paid Rs. 3.20 per hour. How many hours does he labour for if he earns Rs. 432 in four weeks?
A. 160 B. 175 C. 180 D. 195
Explanation: Assume the man works x hours of overtime.Now, the total number of hours worked in four weeks is (5 x 8 x 4) = 160.432 = 160 x 2.40 + x x 3.20,432 − 384 = 48 = 3.20x.x equals 15.As a result, total labour hours = (160 + 15) = 175.
