A can finish a work in 33 days and B can finish the same work in one-third the time taken by A. Working together, what part of the same work can they finish in 5 days?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. .
A's time = 33 days
B's time = 33/3 = 11 days
Combined Rate of (A + B) = (1/33 + 1/11) = 4/33 work per day
Work done in 5 days = (4/33) × 5 = 20/33 of the work
