in a particular city, buildings under residential category was numbered as 1 to 100. shops were numbered between 150 to 200(only prime numbers). how many times does the number 6 appear?

• in 1 to 100 we get 20 six i.e 6,16,26,36,46,56,60,61,62,63,64,65,66(2),67,68,69,76,86,96=20
  in 150 t0 200 we get only two =163,167=2
  total=20+2=22
