Since given triangle is equilateral
So, the ratio of centroid on median 2 : 1 or PG : GA = 2 : 1
(PG + GA) : (PG - GA) = 2 + 1/2 - 1 = 3 : 1
So, the ratio of centroid on median 2 : 1 or PG : GA = 2 : 1
(PG + GA) : (PG - GA) = 2 + 1/2 - 1 = 3 : 1

Given Information:
PA is the median of the equilateral triangle PQR and G is the centroid of the triangle.
Concept of Centroid in an Equilateral Triangle:
- In an equilateral triangle, the centroid divides the median in the ratio 2:1.
- This means that PG:GA = 2:1.
Finding the Ratio of (PG + GA)(PG - GA):
- Let's assume PG = 2x and GA = x (based on the ratio 2:1).
- (PG + GA) = 2x + x = 3x
- (PG - GA) = 2x - x = x
- Therefore, the required ratio is (3x)(x) = 3x^2
Calculating the Ratio:
- We have found that the ratio is 3x^2.
- Since PG:GA = 2:1, we can substitute x = 1.
- Therefore, the ratio becomes 3(1)^2 = 3.
Final Answer:
- The ratio of (PG + GA)(PG - GA) is 3.
- Hence, the correct answer is option 'B' (3).
