Q-p/Q-q/Q-r = 2:5:7


Q-p = 2K                  ........1


Q-q = 5k                  ..........2


Q-r = 7k                 .........3


adding all these eq


3Q -(p+q+r) = 14k         ...........4


p+q+r/2 = Q              (given)


using this eq 4 becomes


Q = 14k


putting Q in 1 ,2 ,3


p = 12k , q = 9k , r = 7k


ratio = p:q:r = 12:9:7
