4.Ranjan and Renu can do a piece of work in 20 and 30 days Ranjan worked for 5 days after days then Renu entered to work Find in what time both can finish the work?

please say how to solve this question madam am getting answer 9 days

Total units of work to be done =60 units in one day both ranjan and renu can do 5 units of work ranjan alone can work for 5 days and completed almost 15 units of work after 5 days renu joined him so the rest 45 units of work can be done by both in 9 days so the total time taken by both is 9+5=14. Thank you :)
