Out of 100 families in the neighbourhood, 45 own radios, 75 have TVs, 25 have VCRs. Only 10 families have all three and each VCR owner also has a TV. If 25 families have radio only, how many have only TV?

    No. of families has all three = 10.
    No. of families has radio only = 25.
    No. of families that has TVs only,
    = No. of families have TVs - No. of families have VCRs - No. of families have all three = 75 - 25 - 10 = 40.
    So, there 40 families that have TVs only.
