Answer 2

Answer:

this ur solution ok follow me

Step-by-step explanation:

Let the work be considered to have 36- units.

In 1- day P+Q can do=36/18= 2- units

In 1- day P+R can do= 36/12=3- units

In 1- day R+S can do= 36/9= 4- units

So P+ Q+ R can do in 1- day= (2+3+4)/2 = 4.5- units

So in 1- day Q- alone can = (4.5- 3) =1.5-units.

Therefore Q can complete the work alone in = 36/1.5= 24- days.
