Question

I am two digit number, my Ones digit is
double of my Tens digit. The difference of my

digits is four.​

Answer 1

Explanation:

You can represent your number like:

x = 10 * a + b

where:

a = tens digit

b = ones digit

Two of my divisor are 8 and 12 mean you must find least common multiple of 8 and 12

Least Common Multiple ( 8 , 12 )= 24

This mean x = 24

b = 2 , a = 4

Proof:

x = 10 b + a = 24

x = 10 b + a =

10 * 2 + 4 =

20 + 4 = 24

Answer 2

Answer:

Your number is X

Explanation:

Your number is x.

x = 10 a + b

My tens digit is double of my ones digit means:

a = 2 b

Now:

The sum of my digit is nine means:

a + b = 9

Replace a with 2 b in this equation.

2 b + b = 9

3 b = 9

b = 9 / 3

b = 3

a = 2 b = 2 ∙ 3 = 6

x = 10 a + b

x = 10 ∙ 6 + 3 = 60 + 3 = 63

Your number is 63
