Question

I am a three digit number, I have no even digit, only one digit of mine composite, my tens digit is four less than my ones digit, my ones digit is two more than my hundreds digit

Answer 1

$i)Ones \:place \: digit = 9 \:(composite\: number)$

$ii)Tens \:place \:digit$

$= Ones \:place \:digit - 4$

$= 9 - 4$

$= 5 \: (Odd \: number )$

$iii) Hundreds \: place \:digit$

$= Ones \:place \:digit - 2$

$= 9 - 2$

$= 7\: ( Odd \: number )$

Therefore,

$\red{Required \: three \: digit \: number }$

$\green { = 759}$
