At first place we can select 5 out of 6 numbers (Excluding 0)
At second place we can select 5 again (Not repeating presvious one but including 0 this time)
At third place we can select 4 out of remaining as we can't repeat 2 which we have already selected
Hence....5*5*4=100

the number that will be formed will be 3 digit number and we have digits 3, 4, 5, 0, 6, 7
so in the first place we can fill 3, 4, 5, 6 and 7 we can't fill 0 at first place so total no of ways at first place is 5 ways
then in second place we can include 0 also but the number that we fill at first place will not so the total no of ways to fill 2nd place are 5
then in the 3rd place we can't fill that two numbers that we fill at first and second place so in the third place we have 4 ways to fill the digits
the answer is 5*5*4=100ways
