If we write down all the natural numbers from 259 to 492 side by side get a very large natural number 259260261....491492259260261....491492.

How many 8's will be used to write this large natural number?

  • A.32
  • B.43
  • C.52
  • D.53

Answer: D

58, there are 200 natural numbers so there will be 2×20=40 8's

From 459 to 492 we have 13 more 8's and so answer is 40+13= 53
