p + q + r = 480

q = 2p

or p = q/2

r = q/2

q/2 + q + q/2 = 480

2q = 480

q = 240

r = q/2 and p = q/2 = 120

so,

r = p = 120 and q = 240

Answer 2

Answer:

p + q + r = 480

q = 2p

or p = q/2

r = q/2

q/2 + q + q/2 = 480

2q = 480

q = 240

r = q/2 and p = q/2 = 120

so

r = p = 120 and q = 240
