If Suresh and Mahesh can do a work in 12 days, Mahesh and Ramesh in 15 days, Suresh and Ramesh in 20 days ,how long will each Suresh, Mahesh and Ramesh take to finish the work?​

Answer 1

Step-by-step explanation:

Mahesh and suresh can do a work in =12days

mahesh and suresh 1 day work = 1/12

mahesh and ramesh can do work in = 15 days

their one day work= 1/15

suresh and ramesh can do work in = 20 days

their one day work = =1/20

so, the total time all of them take to complete the work is = 1/12+1/15+1/20

= 12/60 days
