$A$ sum of money is to be distributed among $A, B, C$ and $D$ in the proportion of $5: 2: 4: 3$. If $C$ gets ₹ $1000$ more than $D$,what is $B$'s share (in ₹)?

If $A: B = 7: 5$ and $B: C = 9: 11,$ then $A: B: C$ is equal to

The income of $A, B$ and $C$ are in the ratio $7: 9: 12$ and their spendings are in the ratio $8: 9: 15$. If $A$ saves $\frac{1}{4}$th of his income,then the savings of $A, B$ and $C$ are in the ratio of:

$10 \ yr$ before,the ratio of ages of $A$ and $B$ was $13: 17$. After $17 \ yr$ from now,the ratio of their ages will be $10: 11$. The present age of $B$ is (in $yr$):

Three numbers are in the ratio $5:6:7$. If the product of the numbers is $5670$,then the greatest number is:

$A$ and $B$ together have ₹ $1210$. If $\frac{4}{15}$ of $A$'s amount is equal to $\frac{2}{5}$ of $B$'s amount,how much amount (in ₹) does $B$ have?
