How many times 3 occur from 3 to 3333

• Under 100: 18 such numbers.
  100-199: 19
  200-299: 19 (as for other 100s not including 300s)
  300-399: 100
  
  So under 1000: 100 + 18 + 8 * 19 = 270
  1000-1999: 271
  2000-2999: 271
  3000-3333: (not including 3333): 333.
  
  270+271+271+333 = 1145,

• Under 100=20 (3,13,23,30,31,32,33,34,35,36,37,38,39,43,53,63,73,83,93)
  Under 1000= 20*10+100=300
  Under 2000= 300+300=600
  Till 2999=600+300=900
  Now till 3333= 334+20+20+20+8+900=1302
