1) To form a number greater than 5000, the thousands place must be filled with 5 (or) 6 (or) 7. = 3 ways.
2) After filling the thousands place we are left with 4 numbers(because repetition is not allowed) = 4 ways.
3) After filling the hundreds place we are left with 3 numbers for 10's place = 3 ways.
4) After filling the 10 place with 3 numbers we are left with 2 numbers = 2 ways.
Total Numbers formed = 3 * 4 * 3 * 2
= 72 ways.
Hope this helps!
