Three numbers are in the ratio $\frac{1}{2}: \frac{2}{3}: \frac{3}{4}$. The difference between the greatest and the smallest numbers is $36$. The numbers are:

If $A$ and $B$ are in the ratio $3: 4$ and $B$ and $C$ are in the ratio $12: 13$,then $A$ and $C$ will be in the ratio:

If $50$ fewer candidates had applied and $25$ fewer had been selected,the ratio of selected to unselected candidates would have been $9:4$. How many candidates had applied if the initial ratio of selected to unselected candidates was $2:1$?

What should be subtracted from $15, 28, 20,$ and $38$ so that the remaining numbers are in proportion?

$A$ sum of $Rs. 86700$ is to be divided among $A, B$ and $C$ in such a manner that for every rupee that $A$ gets,$B$ gets $90$ paise and for every rupee that $B$ gets,$C$ gets $110$ paise. $B$'s share will be (in $Rs.$):

The ratio of the number of boys and girls in a school is $8: 12$. If $50 \%$ of boys and $25 \%$ of girls are getting scholarships for their studies,what is the percentage of school students who are not getting any scholarships (in $\%$)?
