₹ $600$ is divided among $A, B$ and $C$. If $\frac{2}{5}$ of $A$'s share plus ₹ $40$,$\frac{2}{7}$ of $B$'s share plus ₹ $20$,and $\frac{9}{17}$ of $C$'s share plus ₹ $10$ are all equal,then $A$'s share is (in ₹):

If $\frac{A}{3} = \frac{B}{2} = \frac{C}{5},$ then what is the value of the ratio $(C+A)^{2} : (A+B)^{2} : (B+C)^{2} ?$

Two numbers are in the ratio $1: 2$. If $7$ is added to both,their ratio changes to $3: 5$. The greatest number is

$A$ man divides his property such that the ratio of his son's share to his wife's share and the ratio of his wife's share to his daughter's share are both $3:1$. If the daughter gets $Rs. 10000$ less than the son,then the value (in $rupees$) of the whole property is:

$A$ bag contains $10$-paise and $25$-paise coins in the ratio of $17:6$. If the total money in the bag is $Rs. 112$,the number of $10$-paise coins is:

If $378$ coins consist of $Rs. 1$,$50$ paise,and $25$ paise coins whose values are in the ratio of $13: 11: 7$,the number of $50$ paise coins will be:
