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:

The ratio between the present ages of $P$ and $Q$ is $5:7$ respectively. If the difference between $Q$'s present age and $P$'s age after $6$ years is $2$,what is the total of $P$'s and $Q$'s present ages (in years)?

The ratio of the ages of the father and mother was $11: 10$ when their son was born. The ratio of the ages of the father and mother will be $19: 18$ when the son is twice his present age. What is the ratio of the present ages of the father and mother?

If $Rs. 510$ is divided among $A, B, C$ in such a way that $A$ gets $\frac{2}{3}$ of what $B$ gets and $B$ gets $\frac{1}{4}$ of what $C$ gets,then their shares are respectively:

₹ $900$ is divided among $A, B, C$; the division is such that $\frac{1}{2}$ of $A$'s money $= \frac{1}{3}$ of $B$'s money $= \frac{1}{4}$ of $C$'s money. Find the amount received by $A, B,$ and $C$.
