Answer 2

Answer:

Original no. = 31*3 = 93

Step-by-step explanation:

Let the digit at unit place be x .

Now, according to question, ten's digit = 3x

Reversed number : 10*(x) + 3x = 13x

Original Number = 3x*(10)+x = 31x

So, Original-New = 31x-13x=54

                             ⇒ 18x =54

                             ⇒ x=3

Solution check : 93-39=54
