Question

6 workers can construct 10m long

wall in 4 days in how many days 2 workers can construct 15m
long wall?​

Answer 1

• 18 days

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
