Christopher Langan, Test Master. 4.There are 4537 four digit-numbers with no digit repeated.
Explanation :
So we have 10 numbers, which are 0,1,2,3,4,5,6,7,8,9.
And we have to make four digit numbers with no reputation.
So we have four places which are THOUSANDS - HUNDREDS - TENS - ONES, for ONES place we have 7 ways of filling numbers ; for TENS place we have 8 options left; for HUNDREDS place we have 9 options ; for THOUSANDS we have 9 options left.
By the PRINCIPLE OF COUNTING,

When there are m ways to do one thing,
and n ways to do another,
then there are m×n ways of doing both.

So, we have four ways which are 9*9*8*7, on multiplying, we will get our answer which is 4537
