Question

find value of K , 9th question

Answer 1

(3p+2q)/(5q-2r)=k

3p +2q =5qk -2rk ------(1)

(3q+2r)/(5r -2p) =k

3q +2r = 5rk -2pk ----------(2)


(3r +2p)/( 5p -2q) =k

3r + 2p = 5pk -2qk. ---------(3)


add equation (1) +(2) +(3)

3(p + q + r) +2(p + q + r) = 5k(p + q + r) -2k(p + q +r)


5(p + q + r ) = 3k (p + q + r )

k = 5/3
