If A stands for add, B for subtract, C for multiply and D for divide, then for what does $4$ A $3$ B $3$ A $2$ stand?

If '$\times$' stands for addition, '$<$' stands for subtraction, '$+$' stands for division, $\text{'}>\text{'}$ stands for multiplication, '$-$' stands for equal to, '$÷$' for greater than, and '$=$' stands for less than, which of the following equation is true?

If,
$\to$stands for subtract,
$\leftarrow$stands for add,
 stands for multiply,
stands for divide,
stands for greater than, 
stands for equal to,

then which of the following alternatives is true?

If 'x' stands for addition,
'y' stands for subtraction,
'z' stands for divide and 
'p' stands for multiplication, 
then what is the value of  $(7 \mathrm{p} 3) \mathrm{y} 6 \mathrm{x} 5 = ?$

If $A$ stands for not equal to $\left(\ne \right)$

$B$ stands for greater than $\left(>\right)$ 

$C$ stands for not less than $\left(\nless \right)$

$D$ stands for equal to $\left(=\right)$ 

$E$ stands for not greater than $\left(\ngtr \right)$ 

$F$ stands for less than $\left(<\right)$

Then according to the given premises $\left(4x F 5y\right)$ and $\left(5y E 3s\right)$ which inference is correct?

If '$+$'stands for subtraction, '$÷$'stands for addition, '$-$'stands for multiplication and '$\times$'stands for division, then which one of the following equations is correct?

If $x$ stands for $+$, $y$ stands for $-$, $z$ stands for $÷$ and $p$ stands for $\times$, then what is the value of $10 \mathrm{p} 2 \mathrm{x} 5 \mathrm{y} 5$?

If $\times$ stands for addition,
$÷$ stands for subtraction,

$+$ stands for multiplication

$-$ stands for division, then $\left(20\times 6÷6\times 4\right)$ is equal to
