The hundreds digit and the ones digit of a three digit number are the same. The sum of its tree digits are 16. If the tens digit

tensa zangetsu [6.8K]

Step-by-step explanation:

Let us denote the three digit number by $abc$ , where $a$ is the hundreds digit, $b$ is the tens digit and $c$ is the ones digit.

Hundreds digit = $a$ = Ones digit = $c$

Sum of digits = $a+b+c=16$

So, $2c+b=16$

On exchanging tens and ones digit, value increases by 45. So $acb$ is 45 greater than $abc$ .

$acb-abc=45$

$100a+10c+b-100a-10b-c=45\\9c-9b=45\\c-b=5$

$2c+b=16,c-b=5\\3c=21\\c=7=a\\b=2$

∴ Required number is 727
