Answer:
60 days
Step-by-step explanation:
Abinaya can do in 1 day = 1/(5*20) = 1/100 part
Bhadrinath's can do in 1 day = 1/(30*5) = 1/150 part
both can do in 1 day = Abinaya's 1 day + Bhadrinath's 1 day =1/100+1/150
=(6+4)/600= 10/600=1/60 part
time to complete the work by both = 1/(1/60) = 60 days
