Answer:
Step-by-step explanation:
We begin with the fact that P + Q + R = 25300. Now we need to state all of those variables in terms of just one, since we can't have more than one unknown in an equation.
If Q is half as much as P, then
Q = 1/2 P
If R has twice as much as Q, then
R = 2Q, but since Q = 1/2P then
R = 2(1/2P) which is just P. So
R = P and the equation then becomes
P + 1/2P + P = 25300 and
R also is 10120.
Since Q is half of that,
Q = 5060
