Question

The ratio of the salaries of A and B is 8: 9. If A's salary is increased by 50% and B's salary is reduced by 25%, their ratio becomes 16:9. What is the salary of A?

• A. Rs 22000
• B. Rs 28500
• C. Rs 37000
• D. Cannot be determined
• E. None of these

Answer 1

The correct option is D Cannot be determined

A's salary $=Rs.8x$ and B's salary $=Rs.9x$
According to the given condition:
$\frac{8x\times 150\%}{9x\times 75\%}=\frac{16}{9}$
$\Rightarrow \frac{8x\times \frac{150}{100}}{9x\times \frac{75}{100}}=\frac{16}{9}$
$\Rightarrow \frac{12x}{\frac{27x}{4}}=\frac{16}{9}\Rightarrow \frac{48}{27}=\frac{16}{9}$
Hence, A's salary cannot be determined.
