Answer 1

Answer:

,

Explanation:

Given: The sum of the digits is 9. & The number obtained by Interchanging the digits of a two – digit number is 9 more than the Original number.

Need to find: The Original number?

⠀

❍ Let's consider that the two digits be x and y respectively.

Hence,

Original number = (10x + y).

⟹x+y=9

⟹y=9−x

The number obtained by Interchanging the digits of a two – digit number is 9 more than the Original number.

⠀10y+x=10x+y+9

9y=9x+9

y=x+1

x+1=9−x

2x=8

⇢x= 8/2

X=4

x+y=9

⇢4+y=9

⇢y=9−4

y=5

Number=10x+y

↠Numebr=10(4)+5

↠Number=40+5
