For the number to be divisible by 10, unit digit should be 0.

Thus, 0 is fixed at a unit place.

Therefore, the remaining 5 places should be filled with 1,3,5,7,9.

The remaining 5 vacant places can be filled in 5! ways.

Hence, the required number of 6 digit numbers which are divisible by 10=5!=120
