Question

How many different numbers can be formed out of all the digits of 111223? How many of
these are greater than 300000?
Please help. ​

Answer 1

Answer is 120

Step-by-step explanation:

So for number greater than 300000

we have to fix 3 at starting and once we fix 3 all the number will be greater than 300000.

so, at first we fix 3 so we have to put remaining digit that can be but in 5x4x3x2x1 ways = 120 ways. (using permutations)

so 120 numbers greater than 300000 can be formed
