A jewelry store is featuring three rings -- one with a large ruby, one with a diamond, and one with a sapphire.
The total price of the three rings is somewhere between $20,000 and $50,000.
The price of the ruby ring is twice the difference between the prices of the diamond and sapphire rings.
The price of the diamond ring is four times the difference between the prices of the sapphire and ruby rings.
The price of the sapphire ring is an exact multiple of $2,000.
Determine two different sets of possible prices for the three rings.
