We have to consider nos from 300 to 999

Now the first digit from right - it has to start from 3 since it is greater than 299

Therefore the first digit can start with: 3, 4, 5, 7, 9 (total of 5 option)

The second digit can be: 0, 2, 3, 4, 5, 7, 9 (total of 7 options)

The third digit can be: 0, 2, 3, 4, 5, 7, 9 (total of 7 options)

Therefore total no. of ways we have = 5 * 7 * 7 = 245 ways

(More over here it has asked for different three digit number and not different digits so we can consider the 333, 444, 555,666,777,888 and 999 as they all are different numbers)
