  1. A \(\left(\frac{19}{2}, 6\right)\)
  2. B \(\left(\frac{9}{2}, 4\right)\)
  3. C \(\left(8, \frac{13}{2}\right)\)
  4. D \(\left(\frac{11}{2}, \frac{11}{2}\right)\)

Answer & Solution

Correct Answer

(A) \(\left(\frac{19}{2}, 6\right)\)

Step-by-step Solution

Detailed explanation

We know that, centroid divides median in the ratio 2:1. \(\begin{aligned}(7,5) &=\left(\frac{2 x+2}{2+1}, \frac{2 y+3}{2+1}\right) \…
