What is the two digit numeral whose units' digit is 5 more than its tens digit and whose value equals 3 times the sum of these digits?
27.
Let the first (tens) digit be x. Then, since the units digit is the tens digit plus 5, the second (units) digit is (x + 5) and the number is:
10x + (x + 5) = 11x + 5.
And 3 times the sums of its digits is:
3(x + (x + 5)) = 3(2x + 5)
= 6x + 15
But this is equal to the number, so:
11x + 5 = 6x + 15
⇒ 5x = 10
⇒ x = 2
⇒ (x + 5) = (2 + 5) = 7
So the number is 27.
Checking: 3 x (2 + 7) = 3 x 9 = 27

How many 3 digit numbers are formed using digits 1-7?
To form a three-digit number using the digits 1-7, we can choose any of the 7 digits for each of the three places (hundreds, tens, and units).

How many 3 digit combinations using digits 0 to 9 repeating allowed?
To find the number of 3-digit combinations using the digits 0 to 9 with repetition allowed, we consider that each digit can be any of the 10 digits (0-9). Since there are 3 positions in the combination, the total number of combinations is calculated as (10 \times 10 \times 10), which equals 1,000. Therefore, there are 1,000 possible 3-digit combinations.
