Options:
Explanation:
Work done is inversely proportional to the number of workers when the total work is constant.
If 15 masons take 12 days, then total work = 15 × 12 = 180 mason-days.
For 20 masons, days required = 180 ÷ 20 = 9 days.
So, 20 masons will complete the wall in 9 days. Question Screenshot
