We also offer 110 free questions at http://www.free-pm-exam-questions.com . We are a PMI Registered Education Provider. Answer and Explanation: The Correct Answer is B. As 10 engineers reported to you before the recruitment exercise, the total project team size was 11 and the number of communication channels was 11*10/2 = 55. After the recruitment of two engineers the new team size is 13 and the communications channels are now 13*12/2 = 78. The additional communication channels therefore total 78-55 = 23.
