If $A = \frac{4}{5}$ of $B$ and $B = \frac{5}{2}$ of $C$,then the ratio of $A : C$ is

$Rs. 2186$ is distributed among $A$,$B$,and $C$. If the money given to them is decreased by $Rs. 26$,$Rs. 28$,and $Rs. 32$ respectively,then the ratio of their shares becomes $9: 13: 8$. What is the amount (in $Rs.$) given to $A$?

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:

In a college,$150$ students of $MBA$ are enrolled. The ratio of boys to girls is $7:8$. There are three disciplines in the college: Marketing,$HR$,and Finance. In the Marketing discipline,there are $50\%$ girls of their total number and the boys are $40\%$ of their total number. In the $HR$ discipline,girls are $30\%$ of their total number while boys are $30\%$ of their total number. The Finance discipline has girls $20\%$ of their total number and the boys are $30\%$ of their total number. $7$ boys and $9$ girls are in $HR$ and Marketing both. $6$ boys and $7$ girls are in $HR$ and Finance both. $5$ boys and $8$ girls are in Marketing and Finance both. $2$ boys and $3$ girls are enrolled in all the three disciplines. By what percent is the number of boys in the Marketing discipline more than the number of girls in the $HR$ discipline?

The sum of three numbers is $124$. If the ratio between the first and second is $2:3$ and that between the second and third is $7:9$,then the third number is

If $P: Q: R = 2: 3: 4,$ then find $\frac{P}{Q}: \frac{Q}{R}: \frac{R}{P} ?$
