Expressions (pEq) and (qEr)

What is the total number of circles in the given figure below?

In a certain mode 

        $P$ stands for $+$

       $Q$ stands for  $-$

       $R$ stands for $\times$

       $S$ stands for $÷$

Then number corresponding to $6R8S1R3Q5P7Q4P2$ is

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

If $\times$means $-$,$+$ means $÷$,$-$ means $\times$,$÷$ means $+$ then $15-2÷900+90\times 100=$?

A number consists of two digits. If the digits interchange places and the new number is added to the original number, then the resulting number will definitely be divisible by:

In a certain office, $\frac{1}{3}$ of the workers are women, $\frac{1}{2}$ of the same are married and $\frac{1}{3}$ of the married women have children. If $\frac{3}{4}$ of the men married and $\frac{2}{3}$ of married men have children, then what part of the workers without children.
