Question
Amit and BK working together can finish a particular
task in 90 days, while BK and Chiku working together can complete the same task in 70 days. Determine the number of days it would take for Amit to complete 80% of the task individually, given that Amit is 40% less efficient than Chiku.Solution
ATQ, Let the total work be 630 units. (LCM of 90 and 70) Amount of work done by Amit and BK together in one day = 630/90 = 7 units Amount of work done by BK and Chiku together in one day = 630/70 = 9 units Difference between the efficiencies of Amit and Chiku = 9 – 7 = 2 units Amount of work done by Chiku alone in one day = 2/0.40 = 5 units Amount of work done by Amit alone in one day = 0.6 × 5 = 3 units Time taken by Amit alone to complete 80% work = 0.8 × (630/3) = 168 days
