The salaries of A, B and C are in the ratio $3 : 5 : 7$. If these salaries are increased by $50\%$, $60\%$ and $50\%$ respectively, then the ratio between new salaries is:

The salaries of A and B are in the ratio $8 : 9$. If the salary of A is increased by $50\%$ and that of B is decreased by $25\%$, then their new salaries are in the ratio $16 : 9$. How much is the original salary of A?

Mark ($✓$) against the correct answer in each of the following:

The total salary of A, Band Cis $\mathrm{Rs}. 144000$ and they spend respectively $80\%$, $85\%$ and $75\%$ of their salaries. If their savings are in the ratio $8 : 9 : 20$, what is C's salary ?

The ratio between the expenditure and the saving of a man is $26:3$. If his monthly income be $₹21750$, what is his monthly saving?

$₹1470$ are distributed among A, B, C in such a way that on decreasing the share of each by $₹50$, the remaining amounts are in the ratio $1:3:2$. How much is obtained by C ?

A sum was divided among A, B and C in the ratio $2 : 5 : 9$. If A's share be $₹2500$, then the total amount is :

$₹940$ are divided between A and B in such a way that the fifth part of A and the eighth part of B are in the ratio $3 : 4$. Then, A's share is :

$₹600$ are divided among A, B and C in such a way that $₹40$ more than $\frac{2}{5}$ of A's part, $₹20$ more than $\frac{2}{7}$ of B's part and $₹10$ more than $\frac{9}{17}$ of C's part are equal. A's share is :

The cost price of $5$ bananas and $4$ apples is the same as the cost price of $3$ bananas and $7$ apples. What is the ratio between the values of $1$ banana and $1$ apple ?
