Question

Michael took a survey on a social media site of 200 of his friends who identified as fans of a certain series of science-fiction movies. He found that, of the 150 of his friends born on or before the year 1990, 80% said they were fans only of the earlier movies, while the remainder were fans only of the later movies. Of the remainder of his friends, however, 90% said they were fans only of the later movies, while the remainder were fans only of the earlier movies.

In the table below, select the total number of people surveyed who were born after the year 1990 and the total number of people surveyed who preferred the earlier movies.

This is an easy one

200 total friends --> 150 were born on or before 1990, so remaining (200 - 150 = ) 50 were born after 1990.  This is the first blank

Of the 150 were born on or before 1990, 80% were fans only of earlier movies = 80% * 150 = 120
In remainder friends i.e., 50 friends, 10% were fans of earlier movies = 5 
So total = 125  This is second blank

Born After 1990	Fan of Earlier Movies
		50
		75
		100
		125
		150
		175

Born After 1990	Fan of Earlier Movies
		50
		75
		100
		125
		150
		175
