Question

The average between are two name two digit number and the number obtained by interchanging the digit position of its digit is 36 what is the difference between the two digit of the number

Answer 1

Answer:

difference between the two digit of the number = 4

Step-by-step explanation:

Let Say  number = xy

interchanged number = yx

Value of original number = 10x + y

Value of interchanged number = 10y + x

Difference between two numbers = 36

| 10 y + x - 10x - y | = 36

=> | 9y - 9x | = 36

Dividing by 9 both sides

=> | y -x| = 4

so y - x = 4

or x -y = 4

difference between the two digit of the number = 4
