Of the 45 families in a locality, 25 families have working mothers and 10 families have retired individuals as members to look after the children at home. Of the families, 8 have both working mothers and retired individuals as members. How many of the families have working mothers but no retired individuals as members?

Total families with working mothers = 25 Total families with retired individuals = 10 Families with both working mothers and retired individuals = 8

We want to find out the number of families with working mothers but no retired individuals.

We can use the formula for finding the number of families with working mothers but no retired individuals:

Number of families with working mothers but no retired individuals = Total families with working mothers - Families with both working mothers and retired individuals

Number of families with working mothers but no retired individuals = 25 - 8 = 17

So, there are 17 families with working mothers but no retired individuals as members.
