Question

If $x\text{and}y$ are directly related and $x$ = 6, then find $y$ when the constant of proportionality is 2.

• A. 3
• B. 4
• C. 6
• D. 2

Answer 1

The correct option is A 3

Given,
$x\text{and}y$ are in direct proportion
$\text{and}x=6$

$\because \text{Constant of proportionality}=\frac{x}{y}$
$\Rightarrow 2=\frac{6}{y}$
$\Rightarrow y=\frac{6}{2}=3$
