A man completes 5/8 of a job in 10 days. At this rate, how many more days will it take him to finish the job?

A.	5	B.	6
C.	7	D.	7.5

Answer and Explanation

Answer:6

Explanation:
Work Done = 5/8, Balance work = (1 – 5/8) = 3/8
Less work, less days (direct proportion)
Let the required number of days be x
Then, 5/8 : 3/8 :: 10 : x <=> 5/8 * x = 3/8 * 10 <=> x = (3/8 * 10 * 8/5) = 6
