Can APC be greater than 1?Can APS be greater than 1?Can MPC be geater than 1?Can MPS be greater than 1?explain

Yes, APC can be greater than one. This generally happens in such situations where the level of income is so low that consumption is greater than income. However, MPC cannot be greater than one. This is in accordance with the Keynes psychological law of consumption according to which the rate of change of consumption is less than the rate of change of income. 

APS, on the other hand, cannot be greater than one because of the fact that saving is always less than income. Similar to MPC, MPS also cannot be greater than one.
