What the hell is the solution to this puzzle?

A knowledge-loving king decided to reward people who studied hard.

29 gold coins for people taking the bronze.
47 gold coins for people taking the silver.
79 gold coins for people taking the gold.

Well, how many gold coins can people taking the platinum receive?

A: 30
B: 57
C: 78
D: 91
E: 112

We figured out that the given numbers are prime numbers, but nothing else.
