Question 22 (Choice - 2) P (โ€“2, 5) and Q (3, 2) are two points. Find the co-ordinates of the point R on PQ such that PR = 2QR Since PR = 2QR Point R divides PQ in the ratio 2 : 1 Therefore, Coordinates of R = ((2(3) + 1(โˆ’2))/(2 + 1),(2(2) + 1(5))/(2 + 1)) = ((6 โˆ’ 2)/3,(4 + 5)/3) = (๐Ÿ’/๐Ÿ‘,๐Ÿ‘)
