Corona virus

Calculate an estimate of the percentage of GDP (Gross Domestic Product) declined due to the quarantine related to the corona COVID-19 virus that lasts for 2 months, during which time the economic activity is down by 80%.

Result

p =  13.333 %

Solution:

$H=10 + 2 \cdot \ (1-80/100)=\dfrac{ 52 }{ 5 }=10.4 \ \\ p=100 \cdot \ \dfrac{ 12 - H }{ 12 }=100 \cdot \ \dfrac{ 12 - 10.4 }{ 12 } \doteq \dfrac{ 40 }{ 3 } \doteq 13.3333 \doteq 13.333 \%$
