Question

The hundreds digit in a 3-digit number is 4 more than the digit at the tens place and 5 more than the digit at
the ones place. If the sum of the three digits is 12, find the number.​

Answer 1

Answer:

It is 462..

Let the ones digit be x.

According to question the tens digit is x+4 as the tens digit Is 4 more than ones.

Similarly the hundreds digit is (x+4)-2 as the hundreds digit is 2 less than tens.

Now sum of all digit is 12.

Thus, (x+4)-2 + x+4 +x =12

- : x+2 +x+4 +x =12

- : 3x +6=12

- : 3x=6

- : x=2

Therefore ones digit Is x=2

Tens digit is x+4= 6

And hundreds digit is (x+4)-2=4

Hence, required ans is 462
