let 20% be the people who speak both language and the total no. of people be x
then,
20% of x=80
20/100×x=80
x= 80*100/20
=400
no. of people speak English=
80% of 400=80/100*400=80
hence 80 people spoke english
then,
20% of x=80
20/100×x=80
x= 80*100/20
=400
no. of people speak English=
80% of 400=80/100*400=80
