The value of 30 oobers equals the value of 12 darbles, and the value of 5 muxes equals the value of 20 oobers. What is the ratio of the value of 2 muxes to that of 1 darble?

So, we have that 30o=12d 5m=20o

Since we are asked to find the ratio between 2m and 1d, I would find them in function of o so that it simplifies and we remain with our ratio. Thus, d=30/12o=15/6o and m=4o so that 2m=8o. Then the ratio becomes 8o/(15/6)o = 8*6/15 = 8*2/5 = 16/5!
