Answer 1

Answer:

Step-by-step explanation:

Answer 2

Given: Three digits-  0, 3 and 6

To find: The greatest 4 digit number that can be formed by using any one of the given digits twice.

Solution:

We know that whenever we compare any two numbers, we either compare the number of digits  (if different) or we compare the first digit of numbers (if different) followed by digits at places after it (if earlier digits were same).

So to form the greatest 4 digit number using given digits, we need to ensure that the digits are in descending order and the largest of the given number is repeated.

∴ 6 should be the number that we can use twice.

Now, the digits are - 0, 3, 6 and 6.

The greatest 4 digit number will be - 6630

Hence, the required number is 6630.
