Answer/Solution
9 hours
Steps/Work
I believe the answer is B. Please see below for explanation.
if Jamshid can paint a dence in 50 percent less time then Taimour we can infer the following rate J = 2T
if working together they can do the job in 8 hours we can infer 1 = 2T+T * 3 => 1/9
Working alone Taimour can do the job in 1 = 1/9 * hours => 9
