Schools need 4 things to be built, Wood, Clay, Iron and Wheat.
The villagers make 2188 units of Wood per hour
The villagers make 2625 units of Clay per hour
The villagers make 2188 units of Iron per hour
The villagers make 35493 units of Wheat per hour
They have 176236 Wood in stock
They have 248865 Clay in stock
They have 176236 Iron in stock
They have 86879 Wheat in stock
The school is going to cost 256190 Wood, 329385 Clay, 256190 Iron, 73195 Wheat
This means it will take them 1 day, 12 hours 32 minutes before they can enlarge their school as they'll be short of Wood and Iron.
A friendly wizard walks into the village and says "I can transform your stock, 1 for 1 from and to any other type of stock but you must tell me what you want changing to what. This will allow you to build you school sooner."
The villagers are amazed but none of them is very good at maths as they don't have a school yet. They all look confused.
Can you tell them the ideal redistribution of their stock to minimise the time before they can build their school? I can't.
And assume a day is a very long time where they are.

And bonus point if anyone knows what game I'm playing that lead to this.
