Question
if p:q = 3:4 and q:r = 1:2, the
find the value of (4p + 3q + r):(2p + 5q - r)Solution
ATQ,
Given, p:q = 3:4 and q:r = 1:2 Therefore, p = (3q/4) and r = 2q Therefore, (4p + 3q + r) = 4 × (3q/4) + 3q + 2q = 8q And, (2p + 5q – r) = 2 × (3q/4) + 5q – 2q = 9q/2 Required ratio = 8q:(9q/2) = 16:9
