A man completes 5⁄8 of a job in 10 days. At this rate, how many more days are needed to finish the job?

Given data

• Work done in 10 days = 5/8 of job

Concept / Approach

• Rate = (work)/(time). Remaining work = 1 − 5/8 = 3/8.

Step-by-step calculation
Daily rate = (5/8) ÷ 10 = 1/16 of the job per dayTime for remaining 3/8 = (3/8) ÷ (1/16) = (3/8) × 16 = 6

Quick check
Total time = 10 + 6 = 16 days → 16 × (1/16) = 1 job.

Final Answer
6 days
