#### The sum of all possible numbers greater than 10,000 formed by using {1,3,5,7,9} is

In this, we have to find the sum of all numbers greater than 10000 formed by using digits 1, 3, 5, 7, 9, no digit being repeated in any number. We know that any number greater than 10000 would be of 5 digits or more than 5 digits. Also, since we have only 1, 3, 5, 7, 9, and repetition is not allowed, we can make only 5 digit numbers and any number formed by these five digits would be greater than 10000.

Any of the five digits can occupy ten thousand places. Since repetition is not allowed any of the remaining 4 digits can occupy a thousand’s place. Similarly, any of the remaining 3 digits can occupy a hundred’s place. Now, ten’s and unit’s place can be occupied by any of the remaining two digits and last remaining digit respectively.

Therefore, the total numbers formed = 120.

#### Number of different permutations of the word 'BANANA' is

First of all, we have to find the total number of permutations of the word BANANA.

We know the formula that the total number of permutations of n items in which m items are the same is equal to

In the word BANANA, we have six letters.

The total number of permutations of 6 letters = 6!

But in the letter BANANA, we have the letter A repeated thrice and the letter N repeated twice.

So, the total number of permutations of 6 letters =

Thus, number of different permutations of the word 'BANANA' is 60.

#### The number of ways in which 17 billiard balls be arranged in a row if 7 of them are black, 6 are red, 4 are white is

In the above formula, X = total number of entities,

Before solving the question, we are going to assume that all the balls of the same color are identical. This means that one red ball is identical to another red ball. Similarly, one black ball is identical to all the other black balls and one white ball will be similar to other white balls. Now, we are given that out of 17 balls, 7 of them are black, 6 are red and 4 are white. Now, we will arrange these balls in a row. The formula by which we can arrange the total number of entities which contain similar entities is given as:

In this formula, X is the total number of entities, x1 is the number of identical entities of the first kind,

Thus, there are ways in which we can arrange these billiard balls.
