Step-by-step explanation:
Given rajesh and rakesh alone can complete a piece of work in 12 and 24 days respectively .Rajesh started the work and after a few days Rakesh joined him and work was completed in 10 days .After how many days did rakesh join Rajesh?
- According to the question we get
- Piece of work completed by Rajesh in 10 days will be 10 / 12 = 5/6
- Also piece of work completed by Rakesh is 1 – 5/6 = 1/6
- Therefore time taken by Rakesh to complete
- 1/6th of work will be 1/6 x 24 = 4 days.
- Hence Rakesh joined Rajesh after 10 – 4 = 6 days.
