Answer 1

$<b><i>HELLO !$

HERE UR SWEET ANSWER

Let unit digit be 2x

ten digit is 3x

Now ORIGINAL no. is

10(2x)+3x

=20x+3x

=23x




so, the INTERCHANGE digit is
10×(3x)+2x

=30x+2x

=32x

But ACCORDING to questions

INTERCHANGE digit-ORIGINAL no. =27

so,32x-23x=27

=>9x=27

=>x=27/9
=>x=3

so,UNIT DIGIT is 2×3=6

TEN Digit is 3×3=9

if you SATISFIED please MARK AS BRAILIEST.
