1.	What is the sum of the original number and the new number formed if the digits 1 and 9 are interchanged in the number 1009?
Answer» ANSWER: Let the unit digit be y and TENS digit be x NUMBER FORMED = 10x + y Reverse number = 10y + x x + y = 9 (Given)…………………………eq1 10y + x = 10x + y + 27…………………….eq2 9y - 9x = 27 y - x = 3……………………………………..eq3 Solving eq1 and eq3 ,we get x = 3 and y = 6 Original Number = 36 Reversed Number = 63 plz make this as BRAINLEST answer

ANSWER:

Let the unit digit be y and TENS digit be x

NUMBER FORMED = 10x + y

Reverse number = 10y + x

x + y = 9 (Given)…………………………eq1

10y + x = 10x + y + 27…………………….eq2

9y - 9x = 27

y - x = 3……………………………………..eq3

Solving eq1 and eq3 ,we get

x = 3 and y = 6

Original Number = 36 Reversed Number = 63 plz make this as BRAINLEST answer
