Final answer:
To find the number of families that do not read any newspapers in a town, we subtract the number of families that read English newspapers and the number of families that read Hindi newspapers from the total number of families.
Step-by-step explanation:
To find the number of families that do not read any newspapers, we need to subtract the number of families that read English newspapers and the number of families that read Hindi newspapers from the total number of families in the town.
First, we find the number of families that read English newspapers by multiplying the total number of families by 15% (or 0.15). So, 45000 x 0.15 = 6750 families read English newspapers.
Next, we find the number of families that read Hindi newspapers by multiplying the total number of families by 10% (or 0.10). So, 45000 x 0.10 = 4500 families read Hindi newspapers.
To find the number of families that do not read any newspapers, we subtract the number of families that read English newspapers and the number of families that read Hindi newspapers from the total number of families. So, 45000 - 6750 - 4500 = 33750 families do not read any newspapers.
