Step-by-step explanation:

In 20 days,Rima and Radha can reap the whole field.

In 1 day,Rima and Radha together can reap 1/20 th of the field.

For Radha,

In 15 days,Radha can reap 1/2 of the field.

In 1 day,Radha can reap 1/30th of the field.

So,

In 1 day, Rima can reap (1/20-1/30)=1/60 th

[Rima's work=(Radha+Rima's work)-(Radha's work)]

So,Rima will take 60 days to complete the rest work.

Concept-(If a person can do 1/x th work in a day,

then he would take x days to complete the work)
