Download Solution PDFGiven
P is two times as efficient as Q
P is able to complete a piece of work in 40 days less than Q.
Concept
Efficiency is inversely related to time.
Work done = efficiency × time
Calculation
P = 2Q
P:Q = 2:1
The ratio of time = 1:2
1 → 40
P's time = 40
Q's time = 80
Working together, the whole number of days taken by them to complete the work is:
⇒ (80 × 40)/120
⇒ 26.66 = 27 days
Working together, the whole number of days taken by them to complete the work is 27 days.
