Theater M has 25 rows with 27 seats in each row. How many of the seats were occupied during a
certain show?
(1) During the show, there was an average (arithmetic mean) of 10 unoccupied
seats per row for the front 20 rows.
(2) During the show, there was an average (arithmetic mean) of 20 unoccupied seats per
row for the back 15 rows.
OA: E
How? If we take statement 1 then 10*20 seats are unoccupied. therefore rest all are occupied.
Now how we come to know that in the rest of the rows there is no empty seat.
Also we can assume that there are no unoccupied seats in the other rows if we consider statement 1.
Please help to understand the ambiguity..
