Answer 2

Please mark as brainalist answer

Answer:

Efficiency ratio of A,B,and C is 2:3:5

Let in 1day work done by A =2x , B =3x , C= 5x.

Let amount of work = w

A will complete the work in w/2x days.

B will complete the work in w/3x days .

w/2x –w/3x =20

w/e (1/2–1/3)=20

w/e = 20×6=120……….(1)

If they work together in 1 day work done =2x+3x+5x =10x

Total work will complete in w/10x days =(w/e)×(1/10) days =120×1/10 days

Total work will complete in w/10x days=12 days
