Question

If I need three melons to make my pie, and I only have five lemons, how can I succesfully bake my pie without spending any money?

Answer 1

Change the recipe.

Answer 2

The only thing I can think of is the barter system. you trade your lemons for the melons.

Answer 3

But the price of lemons and the price of melons are inproportional! @pratyush5

Answer 4

Then you can't do it, I think. Borrow some melons from someone :)

Answer 5

Do you have options to choose from? @radjoseph
