A person works on a project and completes 5/8 of the job in 10 days. At this rate, how many more days will he it take to finish the job?  Pick.
A) 7  B) 6  C) 5  D) 4  E) 3
Explanation:   Number of days he worked = 10   Work completed =5/8   Let the required number of days =x   Remaining Work to be completed =1−5/8=3/8   More work, more days(direct proportion)   Hence we can write as   (Work) 5/8 : 3/8:: 10 : x   ⇒5/8×x=3/8×10   ⇒5×x=3×10   ⇒x=3×2=6   Answer: Option 6
