Step-by-step explanation:
Given that:-
20 days : 1 year :: 60 days : 2 years
1 year=365 days
2 years=2×365=730 days
20 days : 1 year :: 60 days : 2 years
=>20:365::60:730
Product of Means=365×60=21900
Product of extremes=20×730=14600
Product of extremes≠Product of means
so ,20 days,1 year,60 days,2 years are not in the proportion.
