I'm not sure that there is a contradiction. Using the NIV translation:
They said to him, “That would take more than half a year’s wages [200 denarii]! Are we to go and spend that much on bread and give it to them to eat?” — Mark 6:37
Philip answered him, “It would take more than half a year’s wages [200 denarii] to buy enough bread for each one to have a bite!” —John 6:7
The two verses are not mutually exclusive. Notably, the first doesn't specify how much each person would receive (just saying that the crowd would be given bread).
So putting these two verses together, buying half a year's wages worth of bread would:
There does not seem to be any contradiction between these two statements.
