Question

Charu is facing south. She walks 20 meters towards her left and walk 10 meters, then she takes another left turn to walk 30 meters. In which direction is she standing now from her starting point?

Answer 1

For example, if a baker uses a sack of flour to make pretzels one morning, then the baker cannot use either the flour or the morning to make bagels instead. Part of the cost of making pretzels is that neither the flour nor the morning are available any longer, for use in some other way.
