Answer 1

Answer:

★ Difference = 7 ★

Step-by-step explanation:

Given:

• The difference between two digit number and number obtained by interchanging its digit is 63.

To Find:

• What is difference between the digit of number?

Solution: Let ten's digit of the number be x and ones digit be y

So, Number = (10x + y)

and the number after interchanging digits

• (10y + x )

• Difference between thsese two numbers is 63 •

A/q

→ (10x + y) – (10y + x) = 63

→ 10x + y – 10y – x = 63

→ 9x – 9y = 63 [ Divide each sides by 9 ]

→ 9x/9 – 9y/9 = 63/9

→ x – y = 7

Hence, The Difference between these two numbers is 7
