If 12 workers can complete a project in 15 days, how many days will 10 workers take to complete the same work at the same rate?
A16 days
B18 days
C20 days
D22 days
Explanation
Work done is inversely proportional to the number of workers: Workers × Days = Constant. Therefore, 12 × 15 = 10 × Days. Days = 180 / 10 = 18 days.
