If the plane $7x + 11y + 13 z = 3003$ meets the axes in A, B and C, then the centroid of ΔABC, is
Answer & explanation
Correct answer: option 1
Given plane meets the coordinates axes at A(429, 0, 0), B(0, 273, 0) and C(0, 0, 231).
So, the coordinates of the centroid of ΔABC are
$\left(\frac{429}{3}, \frac{273}{3}, \frac{231}{3}\right) $ i.e. (143, 91, 77).
