Answer:
32 days
Step-by-step explanation:
- R+P can complete the work in 12 days i.e they complete 1/12th of the work in a day.
- P can complete it in 16 days i.e he can complete 1/16th of the work in a day.
- R can therefore complete (1/12 -1/16) th of the work in a day.
=1/48th
R+P worked together for 4 days i.e (1/12 * 4 ) of the work would have been completed.
=1/3rd of the work
Rest =2/3rd of the work
days taken by R= Amt of work / work done by him in a day
=(2/3) / (1/48)=32 days
