The largest number with no repeated digits is 9,876,543,210 although it is 10 digits long, the largest 3 digit number with no repeated digits is 987
The largest three digit prime number whose digits are all primes is 773.

For this type of "the largest number which..." questions, you need to advance from left to right, using the largest possible digit in each case. For the first two digits, that would be 9, for the third digit (the right-most digit), the largest digit which will make this possible is an 8.
999 is the largest 3 digit number because each of the three digits is the largest possible value (9). Whole number simply means that there is no decimal part or fraction.
The largest number with no repeated digits is 9,876,543,210 although it is 10 digits long, the largest 3 digit number with no repeated digits is 987
The largest number with three digits is 999.
Three digits can't possibly add up to 900. The largest possible sum of 3 digits is (9 + 9 + 9) = 27.
The largest three-digit even number that can be formed using the digits 3, 4, and 5 is 543. To determine this, we need to consider the possible arrangements of the digits. Since we want to create an even number, the last digit must be 4. The largest possible number for the hundreds place is 5, and the remaining digit, 3, goes in the tens place. Therefore, the largest three-digit even number using the digits 3, 4, and 5 is 543.
