A town has a total population of 50,000. out of it 28,000 read the newspaper x and 23000 read y while 4000 read both the papers. the number of persons not reading x and y both is

Answer 1

reading x newspaper= 28000-4000
reading y newspaper=23000-4000
total population reading newspaper
=4000+(24000+19000)
=47000
not reading any newspaper =50000-47000=3000

Answer 2

The number of persons not reading X and Y both is 3000.

Step-by-step explanation:

Total population in a town = 50,000

Number of people read the newspaper X = 28,000

Number of people read the newspaper Y = 23,000

Number of people read both newspapers = 4000

Number of people read only newspaper X = 28,000 - 4000 = 24,000

Number of people read only newspaper Y = 23,000 - 4000 = 19,000

Number of people not reading X and Y both = 50,000 - (24,000 + 19,000 + 4000)

= 50,000 - 47,000

= 3000

Hence, the number of persons not reading X and Y both is 3000.
