$A$ man divides his property such that the ratio of his son's share to his wife's share and the ratio of his wife's share to his daughter's share are both $3:1$. If the daughter gets $Rs. 10000$ less than the son,then the value (in $rupees$) of the whole property is:

Find the third proportional to the numbers $4$ and $42$.

$A$ and $B$ are two alloys of gold and copper prepared by mixing metals in the ratio $7:2$ and $7:11$ respectively. If equal quantities of the alloys are melted to form a third alloy $C$,the ratio of gold and copper in $C$ will be

If $A : B = 7 : 9$ and $B : C = 8 : 11,$ find $A : B : C$.
