Step-by-step explanation:
A B C completes 1/15 work in 1 day
A B complete 1/20 work in 1 day
A C complete 1/30 work in 1 day
Days B alone need to complete work= 1/15 - 1/30
= 2/30= 1/15= 15 days
Days C alone needs to complete work= 1/15- 1/20
= 4-3/60= 1/60 = 60 days
Days B and C together needs= 1/ 15+1/60 = 4/60
= 1/15 or 15 days ans
