Answer:

30

Step-by-step explanation:

This is a bit nasty, but you must keep the order in mind. PQR means that Q is the middle letter. M is also the middle letter. That's the easy part. What does MNL mean?

The lettering goes clockwise. MNL is the same thing as QRP. So what is R?

50 + 100 + R = 180

150 + R = 180

R = 180 - 150

R = 30
