Working individually, Emma can wrap presents for 6 hours and Troy can wrap presents in 8 hours. If Emma and Troy work together but independently at the task for 2 hours, at which point Troy leaves, how many remaining hours will it take Emma to complete the task alone?
Choose the correct choice from the following.
A) 30/12	B) 5/12	C) 3/4	D) 2/12	E) 3/5
In first 2 hrs Troy will finish 2/8 = 1/4 of work and Emma will finish 2/6 work so total 1/4 + 1/3 = 7/12 work is finished and 1-7/12 = 5/12 work remaining. Now Emma will take (5/12)*6 = 30/12 hrs to finish it.   So answer is 30/12.
