The Correct Option is A

Solution and Explanation

Consider x as the number of hours for regular work and y for overtime work.
We can establish two equations:
x+y=172........(1)x+y=172........(1)
114y=15100×57x......(2)114y=\frac{15}{100}​×57x......(2)
Upon solving these equations, we find x=160x = 160 and y=12.y = 12.
Therefore, the overtime work amounts to 12 hours.
