Answer:

  • 18 days

Step-by-step explanation:

Remember :

  • Number of workers is inversely proportional to the amount of days required

Here :

  • 6 workers construct 10 m long wall in 4 days
  • Then, for 2 workers to construct the same length, it will take 3 times the amount of time as number of men has been divided by 3
  • 2 workers to construct 10 m long wall = 4 x 3 = 12 days
  • For them to construct 15 m long wall, multiply the number of days by 1.5 as 10 x 1.5 = 15
  • No. of days for 2 workers to construct 15 m long wall :
  • 12 x 1.5 = 18 days
