12 is 60% of 20. You can make 60% into a fraction (60/100) and set that fraction equal to 12/x. You then cross multiply (12*100 and 60*x) to get 1200=60x. You then divide both sides by 60 to get x, which equals 20.

It will take twelve (12) plumbers 9 weeks to install the same number of lines
From the question,
We have that, 18 plumbers can install 540 water lines in 6 weeks,
To determine how long it will take 12 plumbers to install the same number of lines,
First, we will determine how long it will take 1 plumber.
If 18 plumbers can install 540 water lines in 6 weeks
Then,
1 plumber will install 540 water lines in 18 × 6 weeks
18 × 6 weeks = 108 weeks
∴ It will take 1 plumber 108 weeks to install 540 water lines
Now, for the number of weeks it will take 12 plumbers
If 1 plumber can install 540 water lines in 108 weeks
Then,
12 plumbers will install 540 water lines in weeks
Hence, it will take twelve (12) plumbers 9 weeks to install the same number of lines
