Heya

Let the number of days taken by Anita to complete the work be X days and Sheena be x/3 days

Work done by Anita in one day will be 1/x

Work done by Sheena in one day will be 1/(x/3) = 3/x

Work completed by both of them together in one day is 1/60

According to the problem

1/x + 3/x = 1/60

(1+3)/x = 1/60

x= 60×4

x=240

So Anita takes 240 days to complete the work alone
