Given:
Efficiency of M : Efficiency of N = 2 : 1
M can complete a work in 66 days less than N.
Concept Used:
If the total work is constant, then
Efficiency ∝ (1/time)
Formula Used:
Total work = efficiency × total time
Solution:
Efficiency of M : Efficiency of N = 2 : 1
Time taken by M : Time taken by N = 1 : 2
According to the question:
=> 1 unit = 66 days
Time taken by M = 66 days
Total work = 66 × 2 = 132 units
Required time to work together = 132/3= 44 days
