how many 4 are there in between numbers 11 and 100

• answer is 19 ...
  except series of 41 to 50 in all series have only one '4'
  so we can easily calculate no of 4 from 11 to 100 =9 (except in series of 40)
  in 41 to 49 4 is =10 hence total =19

• the answer would be 18.
  because 14,24,34,54,64,74,84,94=8
  40-49:10
  10+8=18

• 19
  41,42,43,44,45,46,47,48,49,40=10
  14.24.34.54.64.74.84.94.44=9
  TOTALY 19

• for any no b/w 2-9(here 4) 20 is the ans when counting starts from 1-100. but here as the counting starts from 11 one 4 will be dropped. so the ans is 20-1=19

• 10-20=1 21-30=1 31-40=2 41-50=10 51-60=1 61-70=1 71-80=1 81-90=1
  91-100=1 so there are 19 4 are there

• 19
  
  as any no. between 1 -100 comes 20 times only
  in this case one 4 is only not in range thats why ans is 20-1 = 19

• 11 to 20 = one 4
  21 to 30 = one 4
  31 to 40 = two 4s
  41 to 50 = ten 4s
  51 to 60 = one 4
  61 to 70 = one 4
  71 to 80 = one 4
  81 to 90 = one 4
  91 to 100 = one 4
