The answer will be 20 as 33 has two 3 so but you don't have to count 33 Twice..
It’s wrong 3 appears 19 times between 1-100
But why you count 33 two times
The answer is 20 only. We have to consider 33 as 2 count not as 1,because we are writing two 3s there
Answer should be 21.
The answer is 19. He has counted 33 twice.
the answer is 21 because their is two times 3 in the figure of 33 so 10+11= 21
