Question

The city of N lives 200,000 inhabitants. Among them, 15% of children and adolescents. Among adult residents, 45% do not work (pensioners, students, housewives, etc.). How many adult residents work?

​

Answer 1

80.000 работает

т.к 15+45=60%

100%х60=0.6х200.000=120.000

200.000-120.000=80.000
