At the equilibrium, the total surplus is the sum of consumer and producer surplus, which is $ \textbackslash$120,000 + \textbackslash$180,000 = \textbackslash$300,000$.  After the price ceiling is imposed, the consumer surplus increases to $\textbackslash$140,000$, while the producer surplus decreases to $\textbackslash$140,000$. The new total surplus is $ \textbackslash$140,000 + \textbackslash$140,000 = \textbackslash$280,000$.  Therefore, the deadweight loss is the difference between the total surplus before and after the price ceiling, which is $\textbackslash$300,000 - \textbackslash$280,000 = \textbackslash$20,000$ . 
At equilibrium in the market of apartments, the consumer surplus is $\textbackslash$ 120,000$ and the producer surplus is $\textbackslash$ 180,000$. The government decide to set a price ceiling. As a result, the consumer surplus becomes $ \textbackslash$ 140,000$ and the producer surplus becomes $\textbackslash$ 140,000$. What is the deadweight loss from the price ceiling?
