Question 870270: In a city there are 15000 families. (3.5)% read news paper 'A' but not 'B' look into advertisements, 25% read news paper 'B' but not 'A' look into advertisements, 50% read both and look into advertisements. It is known that 8000 families read 'A', 4000 read 'B', and 1000 read both A and B then,
i) The number of families look into advertisements is ?,
ii). The no. of families who read at most one news paper is?.
You can put this solution on YOUR website! It is unclear if the 3.5%, 25% and 50% are of the 15000 families of those who read
3.5% of those who read A , 25% of those who read B and 50% of those who read both
280+500+100=880 who read ads if the second choice
525+7500+3750=11775 if the first.
if 1000 read both then at most 11000 read just one.
