2p/r = 30.
p/r = 15.
Statement 1 is sufficient.

p/3r = 5
p/r = 15
Statement 2 is sufficient.

D is the answer.

Note: The ratio p to r can also be expressed using fraction notation to get p/r

Target question: What is the value of p/r ?
Aside: I altered the notation because the two statements are giving us information in fraction form

Statement 1: 2p/r = 30
Divide both sides of the equation by 2 to get: p/r = 15
Since we can answer the target question with certainty, statement 1 is SUFFICIENT

Statement 2: p/(3r) = 5
Multiply both sides of the equation by 3 to get: p/r = 15
Since we can answer the target question with certainty, statement 2 is SUFFICIENT

Answer: D
