The greatest number among the numbers 9642, 8650, 9800, 9500, 7000 is ______. 

Hint:

We have to find the greatest among the numbers given i.e. 9642, 8650, 9800, 9500 and 7000. Firstly we need to compare the digits on the thousand place which are 9, 8, 9, 9 and 7. As we can see greatest digit is 9 but is three times , so, now we will compare the digits in the hundreds place of these three numbers which are 6, 8 and 5. As we can clearly see which digit is greatest among these three so the number with greatest digit is the greatest number among the number given.
