Detailed Solution
Download Solution PDFGiven:
A can do a certain job in 120 days.
B is 60% more efficient than A.
Formula used:
Efficiency of B = Efficiency of A × (1 + 60/100)
Time taken by B = Time taken by A / Efficiency of B
Calculation:
Efficiency of A = 1 job/120 days
Efficiency of B = (1 job/120 days) × (1 + 60/100)
⇒ Efficiency of B = (1 job/120 days) × 1.6
⇒ Efficiency of B = 1 job/75 days
⇒ Time taken by B = 75 days
∴ The correct answer is option 4.
