Directions:- Study the following information carefully to answer the question given below.
Seven plays - A, B, C, D, E, F and G - are to be held on seven consecutive days (starting on Monday and ending on Sunday) not necessarily in the same order. Only one play can be held on one day. Only two plays will held after play G. Only two plays will be held between play F and play G. Only three plays will be held between play B and play E. Play B will not be held on Sunday. Play A will be held before play D and play C (not necessarily immediately before). Play C will be held alter play D (not necessarily immediately after).
If all seven plays are held in the alphabetical order of their names starting on Monday and ending on Sunday, the positions of how many will remain unchanged as compared to the original schedule?
