How many three digit numbers are there in which all the digits are odd...
The number of odd digit numbers are 5 i.e. 1, 3, 5, 7, 9.
So the required number will be formed using only these 5 digits.
Let the 3 digit number be “abc”
So “a” can be replaced by 5 odd digit numbers i.e. 1, 3, 5, 7, 9 and same with “b” and “c”
By using permutation concept the required numbers = 5 × 5 × 5 = 125
∴ The number of three digit numbers in which all the digits are odd is 125.
So the required number will be formed using only these 5 digits.
