Answer 1

$\huge⚘ \bf \ \red{Answer}$

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
