Question

a three digit number has the same digits in ones, tens and hundreds place. if the sum of the digits is 12,what is that number..?

Answer 1

444

Explanation:

Let's change the question a little: I have three numbered chips in a bag. All three chips have the same number written on them. When you add the numbers on the chips together, you get 12.

What number is written on each chip?

You could do it with "math": 12 divided by 3 chips = 4 is each digit

You could do it by deduction: is 2 big enough? No, because three 2's is only 6. Is 3 big enough? No, because three 3's is only 9. Then you get to 4 and see that it must be the answer.

So if each digit of a three-digit number is 4, then the number is what?

4, 4, 4 --> 444
