In a village of 1000 inhabitants, there are three newspapers P, Q and ...
Analysis:
To find the number of persons who read no newspaper at all, we need to subtract the number of persons who read at least one newspaper from the total population of the village.
Given:
- Total population of the village = 1000
- Number of persons who read each newspaper = 500
- Number of persons who read P and Q = 250
- Number of persons who read Q and R = 250
- Number of persons who read R and P = 250
- Number of persons who read all three newspapers = 250
Solution:
Let's calculate the number of persons who read at least one newspaper by adding the number of persons who read each newspaper individually and then subtracting the number of persons who read multiple newspapers more than once.
Persons who read P or Q or R:
- Number of persons who read P = 500
- Number of persons who read Q = 500
- Number of persons who read R = 500
Persons who read multiple newspapers:
- Number of persons who read P and Q = 250
- Number of persons who read Q and R = 250
- Number of persons who read R and P = 250
Persons who read all three newspapers:
- Number of persons who read P and Q and R = 250
Calculating the number of persons who read at least one newspaper:
Number of persons who read at least one newspaper = (Number of persons who read P) + (Number of persons who read Q) + (Number of persons who read R) - (Number of persons who read P and Q) - (Number of persons who read Q and R) - (Number of persons who read R and P) + (Number of persons who read P and Q and R)
= 500 + 500 + 500 - 250 - 250 - 250 + 250
= 1000
Calculating the number of persons who read no newspaper:
Number of persons who read no newspaper = Total population of the village - Number of persons who read at least one newspaper
= 1000 - 1000
= 0
Therefore, there are no persons in the village who read no newspaper at all.
To find the number of persons who read no newspaper at all, we need to subtract the number of persons who read at least one newspaper from the total population of the village.
Given:
- Total population of the village = 1000
- Number of persons who read each newspaper = 500
- Number of persons who read P and Q = 250
- Number of persons who read Q and R = 250
- Number of persons who read R and P = 250
- Number of persons who read all three newspapers = 250
Solution:
Let's calculate the number of persons who read at least one newspaper by adding the number of persons who read each newspaper individually and then subtracting the number of persons who read multiple newspapers more than once.
Persons who read P or Q or R:
- Number of persons who read P = 500
- Number of persons who read Q = 500
- Number of persons who read R = 500
Persons who read multiple newspapers:
- Number of persons who read P and Q = 250
- Number of persons who read Q and R = 250
- Number of persons who read R and P = 250
Persons who read all three newspapers:
- Number of persons who read P and Q and R = 250
Calculating the number of persons who read at least one newspaper:
Number of persons who read at least one newspaper = (Number of persons who read P) + (Number of persons who read Q) + (Number of persons who read R) - (Number of persons who read P and Q) - (Number of persons who read Q and R) - (Number of persons who read R and P) + (Number of persons who read P and Q and R)
= 500 + 500 + 500 - 250 - 250 - 250 + 250
= 1000
Calculating the number of persons who read no newspaper:
Number of persons who read no newspaper = Total population of the village - Number of persons who read at least one newspaper
= 1000 - 1000
= 0
Therefore, there are no persons in the village who read no newspaper at all.
