Question

From $3te756$ take $2e46t2$ in the duodenary scale.

Answer 1

$3te756$ from scale of twelve to decimal is $6\times {12}^0+5\times {12}^1+7\times {12}^2+11\times {12}^3+10\times {12}^4+3\times {12}^5=973938$

$2e46t2$ from scale of twelve to decimal is $2\times {12}^0+10\times {12}^1+6\times {12}^2+4\times {12}^3+11\times {12}^4+2\times {12}^5=733658$

Difference between them is $=973938-733658=240280$

Now we need to represent this in scale of $12$ is:

When $240280$ is divided by $12$ quotient is $20023$ and remainder is $4$
When $20023$ is divided by $12$ quotient is $1668$ and remainder is $7$
When $1668$ is divided by $12$ quotient is $139$ and remainder is $0$
When $139$ is divided by $12$ quotient is $11$ and remainder is $7$
When $11$ is divided by $12$ quotient is $0$ and remainder is $11$

Hence, the difference is $e7074$ in scale of eight.
