• Total families = 2000,
  families with Cars only = 900,
  families with both Cars and Two Wheelers = 607,
  families with no Cars and no Two Wheelers = 100,
  Total families = Cars Family + Two Wheelers Family + Cars and Two Wheeler Family + no Car no Two Wheeler family
  2000 = 900 + Two Wheelers Family + 607 + 100

• since it is given that total no of families is 2000 and no. of families having none=100, so 2000-100=1900.
  x=no. of families having only wheelers.
  now, 1900=900+x-607
  x=1607.

• 1900=only cars + only 2 wheelers +both cars and 2 wheelers
  1900=900+607+only 2 wheelers
  only 2 wheelers=1900-1507
  =393

• 2000=900+607+100+only two wheelers
  no of families having only two wheeler=2000-(900+100+607)
  =393
