Question

The sum of the digits of a 3- Digit number is 18. If the tens digit is the same as the units digit but 3 less than the hundreds digit, Find the number.​

Answer 1

Answer:

Let's work on it,

Hundreds digit = H

Tens digit =T

Units digit = U

What we know here is H=2T &. U = 3T so

2T +T + 3T =18

6T = 18

T= 18/6

T= 3

H= 6 (2T)

U = 9 (3T)

Answer is 639
