A, B and C complete a work in alternate way. If A starts the work followed by B and C then the work gets completed in 38 days but if B starts then the work is completed in 38 days and if C starts it then the work gets completed in 38 days. Find in how many days A alone can complete the work
A 36 days B 30 days C 45 days D 60 days
Answers
Answer:
C 27 DAYS
Step-by-step explanation:
Let the efficiency of A be 1 unit
Total work = 48 x 1 = 48 units
Working alternatively,
Time for which A work in days = days
Work done by A = units
Time for which B work = 6 days
Work done by B = 48 - = units
Efficiency of B = 128/18 units per day
Time taken by B to finish 4 times the work = 192/(128/18) = 27 days
Answer:
The correct answer is option B
Step-by-step explanation:
Let the efficiency of A be 1 unit
Total work = 38 x 1 = 38 units
Working alternatively,
Time for which A work in days = days
Work done by A = units
Time for which B work = 2 days
Work done by B = 38 - = units
Efficiency of B = 128/18 units per day
Time taken by B to finish 4 times the work = 192/(128/18) = 30 days
