  1. If A takes 4/5 days as B takes and working together they require 20/3 days to complete the whole work. What is the efficiency of B?
    1. 62/3%
    2. 16%
    3. 5.55%
    4. 81/3%
Correct Option: A

Efficiency of A + B = 100/(20/3) = 15%
No. of days ( A:B ) = 4 : 5
Efficiency ( A:B ) = 5 : 4

∴ Efficiency of B = (4/9) x 15 = 20/3 = 62/3%
