Q:
A is 50% more efficient than B. They together start the work and 7/12th of work is left after 8 days. Find in what time B alone will complete the whole work.
Answer & Explanation
Answer:
Explanation: Ratio of efficiency of A to B is 3 : 2
Let, In 8 days they complete = (3 + 2) × 8 = 40 units
So, total work = 40 × 12/5 units
Time taken by B alone to complete whole work = 40 × 12/5 ×2 = 48 days
