Detailed Solution
Download Solution PDFGiven:
Raju can complete the work in 10 hours
Ram can complete the same work in 15 hours
Concept:
When two people work together, their combined rate is the sum of their individual rates.
Solution:
⇒ Work done by Raju in 1 hour = 1/10
⇒ Work done by Ram in 1 hour = 1/15
⇒ Combined work done in 1 hour = (1/10) + (1/15) = 1/6
⇒ Time required to finish the work = 1/(Combined work done in 1 hour) = 6 hours
Therefore, Raju and Ram can finish the work together in 6 hours.
