Answer 2

Answer:

Hello everyone! I wanna say you a trick I found the best so as to clear you every doubt on numbers based on digits.

Step-by-step explanation:

To find the total number of X digit number you have to just place X-1 number of zeroes after 9.

For example,

•Total no. of 2 digit numbers= 90(X-1 = 1, thus, one zero after 9)

•Total no. of 5 digit numbers= 90000( X-1 = 4, thus, four zeroes after 9)
