Detailed Solution
Download Solution PDFGiven:
Abraham can complete a work in 9 days, while Andrew can complete the same work in 6 days.
Concept used:
Efficiency = (Total work / Total time taken)
Efficiency = work done in a single day
Calculation:
Let total work is 18 units ( Lcm of 6 and9 )
The efficiency of Abraham is
⇒ 18 / 6 = 3 unit
Again, the Efficiency of Andrew is,
⇒ 18 / 9 = 2 unit
Total Efficiency,
⇒ 3 + 2 = 5 unit
The number of days required is,
⇒ 18 /5 = \(3{3 \over 5}\) days
∴ The correct option is 2
