Answer 1

$\sf \pink {Let}$

$\sf \purple{The \:number =ab} \\ \sf=10a+b$

$\sf \blue {Sum\: of \:digits =9}$

$\sf \green {a+b=9}$

$\sf \orange {Number −27}$

$\sf \purple {=Number \:with\: reversed\: digits}$

$\sf \red {Now}$

$\sf \pink \implies \purple {10a+b−27=10b+a}$

$\sf \green \implies \blue {9(a−b)=27}$

$\sf \red \implies \orange {a−b=3}$

$\sf \blue \implies \green{(a+b)+(a−b)=9+3}$

$\sf \purple \implies \pink {a=6,b=3}$

$\sf \orange \therefore \red {Required \:number \:is\: 63}$

Answer 2

Answer:

Arnav bhaiya this is not good

I know that day I asked the reason for blocking my last ID

that was a joke only nothing else

and that was good only that you blocked my last ID Cinderella151

because I was just going to change that

but now this is my last ID

I am not going to change it

and you remember your sis can find out the reason behind offline

whenever you were offline I understood that your mood is off

but you know I never asked the reason behind this

because I didn't wanted to put salt on injuries
