Question

the population of a village is 15000 among them 9000 read kantipur 7500 read gorkhapatra and 40 %read both magazine find the percentage of the people who don't read both the magazine​

Answer 1

Answer:

Step-by-step explanation:

n(c) =9000

n(G)=7500

n(AunionB)= n(c)+n(G)-n(cintersectionG)

=9000+7500-6000

10,500

=15000

n(A union)=15000-10500

4500=30%

Answer 2

Percentage of the people who don't read both the magazine​ is 30%

Given:

Population of village = 15000

People reading Kantipur = n(k) = 9000

People reading Gorkhapatra = n(g) = 7500

People reading both = n (g + k) = 40%

To Find:

Percentage of the people who don't read both the magazine​

Solution:

Number of people reading both = 40%,

Therefore -

40% of 15,000

= 40/100 × 15,000

= 6,000

Now,

Total number of people reading -

= n(k) + n(g) -n(k + g)

= 9000 +7500 -6000

= 9000 + 1500

= 10,500

The population who do not read = Total population - People who are reading

= 15000 - 10500

= 4500

Percentage population who do not read both -

= 4,500/15,000 × 100

= 450/15

= 30%

Answer: Percentage of the people who don't read both the magazine​ is 30%
