Fig.9: Increase in Demand and Supply Fig.10: Decrease in Demand and Supply
-------------------------------------------------------------------------------------------

1.Outward shift both in Demand and Supply (Fig.9) will result into no change in market price but equilibrium quantity will rise (Q1 to Q2).
2.Inward shift both in Demand and Supply (Fig.10) will result into no change in market price but equilibrium quantity will fall (Q1 to Q2).

1.Outward shift in Demand and inward shift in Supply (Fig.11) will result into a rise in market price (P1 to P2) but no change in equilibrium quantity.

E.g. present land market.

2.Inward shift in Demand and outward shift in Supply (Fig.12) will result into fall in market price (P1 to P2) but no change in equilibrium quantity.

E.g. current landline phone market.
