Question

The sum of the digits of a 2-digit number is 9.
If the tens digit is half of the ones digit, find the
2-digit number​

Answer 1

Answer:

The digit is 36

Step-by-step explanation:

Let the units place be x

Tens place=x/2

x+x/2=9

Taking LCM-

(2x+x)/2=9

3x=9*2        => 3x =18

Therefore;

x=18/3          x=6    (units place)

x/2=6/2    = 3       (tens place)
