If $A: B = 8: 15$,$B: C = 5: 8$,and $C: D = 4: 5$,then $A: D$ is equal to:

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 $x$ runs are scored by $A$,$y$ runs by $B$,and $z$ runs by $C$,then $x: y = y: z = 3: 2$. If the total number of runs scored by $A$,$B$,and $C$ is $342$,the runs scored by each would be respectively:

$Rs. 5625$ are divided among $A, B$ and $C$ such that $A$ receives half as much as $B$ and $C$ together,and $B$ receives one-fourth as much as $A$ and $C$ together. Find the sum of $A$'s and $B$'s share together (in $Rs.$).

In a bag,there are coins of $25 \ p$,$10 \ p$,and $5 \ p$ in the ratio of $1: 2: 3$. If there are $Rs. 30$ in all,how many $5 \ p$ coins are there?

$94$ is divided into two parts in such a way that the fifth part of the first and the eighth part of the second are in the ratio $3:4$. The first part is:
