Detailed Solution
Download Solution PDFGiven:
A is twice efficient than B.
A can work only for 8 hours a day while B can work for 12 hours a day
Formula used:
Men × Day = Total work
Calculation:
Let the time taken by B to complete work be b.
⇒ 2 × 8 × 12 = 1 × b × 12
⇒ b = 192/12
⇒ b = 16
∴ In 16 days, B alone can complete the work.
