A alone can complete a work in 40 days. 20 percent of the same work will be completed by A in how many days?
Answer & explanation
Correct answer: option 1
A = 40 days,
Let's assume efficiency of A as 1.
⇒ Therefore Total work = 1 x 40 = 40 units ..(Efficiency × Days = Total work)
⇒ 20% of 40 = 8 units.
⇒ So, time required for A to complete 8 units of work = \(\frac{8}{1}\) = 8 days.
