​

Answer 1

Answer:

30%

Step-by-step explanation:

Total population=15,000

kantipur=9000

gorkhapatra= 7500

55%

Both magazine=40%

n(k intersection g)=40% of 15,000

=0.4*15,000

=6,000

n(k)=9000

n(g)=7500

n(A union B)= n(k) + n(g) -n(k intersection g)

=9000+7500-6000

=10,500

Population who do no read= Total population -

n(A union B)

=15000-10500

=4500

Percentage population who do not read both

magazine

=4,500/15,000 * 100

=0.3 * 100

=30%
