Answer:
28 days
Step-by-step explanation:
n men will take = 20 days
n - 3 = 24 days
20 - 3 men will take = 20 + 4 days
6 men will take = 20 + (4 × 2)
= 28 days

Answer:
30 days
Step-by-step explanation:
n(20)= (n-3)24
20n= 24n-72
n=18
18 men will complete the work in 20days
15 men will complete the work in 24 days
total work= 360(20*18)
total time taken by 12 men to complete the same work will be
360/12= 30days
