Question

how many numbers greater than a million can be formed with digits 2,3,0,3,4,2,3​

Answer 1

Answer:

Step-by-step explanation:

One million has 7 digits i.e. 6 zeros

So, numbers greater than a million will have atleast 7 digits

−−−−−−−

2,3,4 (3 ways)

6!

​1st place can't be zero

1st place −2− Numbers left (3,0,3,4,2,3)

No. of ways of arranging remaining digits =  3/6 =120

1st place −3− Numbers left (2,3,0,3,4,2)

No. of ways of arranging remaining digits =  6/22 =180

1st place −4− Numbers left (2,3,0,3,2,3)

No. of ways of arranging remaining digits =  6/32 =60

Then, total no. of ways =120+180+60=360
