Answer 2

The largest 5-digit number having three different digits is 99,987.

Step-by-step explanation:

We have to find the largest 5-digit number having three different digits.

Given numbers 98,978, 99,897, 99,987, 98,799

All numbers have three different digits.

We have to compare the numbers to find largest.

In the given numbers, 9 is in ten thousand place in all numbers.

8 and 9 digits are in thousand place.

So, 8 < 9

So, 98,978 and 98,799 cannot be the largest.

Now, compare 99,897 and 99,987.

Here, hundred digit of both numbers are 8 and 9.

So, 8 < 9.

So, the largest number will be 99,987.

Hence, the largest 5-digit number having three different digits is 99,987.
