How many 6-digit numbers can be formed from the digits 0, 1, 3, 5, 7 and 9 which are divisible by 10 and no digit is repeated?

Asked by Abhisek | 1 year ago |  89

Solution :-

number can be divisible by 10 only if its units digit is 0.

Hence, 0 is fixed at units place.

Therefore, the 5 vacant places can be filled by remaining 5 digits.

These 5 empty places can be filled in 5! ways.

Therefore, number of 6-digit numbers = 5! = 120.
