Question

If $x$ and $y$ are inversely proportional then find the value of $a$.

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

Answer: (B)

$2$

When two quantities are in inverse proportional then,

$\Rightarrow x_1\times y_1=x_2\times y_2$

$\therefore 3\times 4=6\times a$

$\Rightarrow a=\frac{3\times 4}{6}$

$\Rightarrow a=2$

Hence, the value of $\text{a}$ is $2$.
