Download Solution PDFGiven:
450 men can finish the construction of an apartment in 20 days.
Concept used:
Total work = Number of workers × Efficiency of each worker × Number of days required
Calculation:
Let the efficiency of each man be M.
Total work = 450 × M × 20 = 9000M
Now, the number of men required to complete the task in 30 days = 9000M ÷ (M × 30) = 300
∴ 300 men can finish the construction in 30 days.
