Question:
<p>Locus of the centroid of the variable triangle OAB has the equation (where 'O' is the origin):</p>
<p>(a) 3x + 4y + 6xy = 0</p>
<p>(b) 4x + 3y - 6xy = 0</p>
<p>(c) 3x + 4y - 6xy = 0</p>
<p>(d) 4x + 3y + 6xy = 0</p>
Step-by-Step Solution
Key Concept: Use centroid formula and establish the locus equation from geometric constraints
<p>This is a standard locus problem requiring additional context from the original problem statement about the triangle OAB.</p>
Correct Answer: C
