In a group of cows and hens, the number of legs are $14$ more than twice the number of heads. The number of cows is 

Which one of the four interchanges in signs and numbers would make the given equation correct?

$(3÷4)+2=2$

If P denotes $÷$, Q denotes $\times$, R denotes $+$ and S denotes $-$, then the value of $18$Q$12$P$4$R$5$S$6$ when simplified gives

If $+$ denote $÷$, $-$ means $\times$, $÷$ means $+$ and $\times$ means $-$, then $36\times 8+4÷6+2-3=?$

It being given that

$$\begin{gathered} > \equiv + \\ < \equiv - \\ + \equiv ÷ \\ - \equiv = \\ = \equiv less than \\ \times \equiv greater than \end{gathered}$$ 

Find which of the following is a correct statement:

If L denotes $\times$, M denotes $÷$, P denotes $+$ and Q denotes $-$, then $8$P$36$M$6$Q$6$M$2$L$3$=?

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

If $+$ means $\times$, $\times$ means $-$, $÷$ means $+$ and $-$ means $÷$, then which of the following gives the result of this equation ?

$175-25÷5÷20\times 3+10$
