Let's say a family husband is working, so if more people works in family, more income for the family. It is an example of direct variation.
If family has less members, more saving (provided that the family has the same amount of income). More members, less saving ( income is still the same). It is an inverse variation.
more members work = more earning in family
more members = less saving in family
More members is in joint variation to earning and saving.
1) Direct variation -- as the independent variable increases so does the dependent variable.
The amount of money a person who is paid hourly makes varies directly with the number of hours worked.
P=kh where P is the pay, h the number of hours, and k, the proportionality constant, is the hourly wage.
2) Inverse variation -- as the independent variable increases, the dependent variable decreases or vice versa.
If family has less members, more saving (provided that the family has the same amount of income). More members, less saving ( income is still the same). It is an inverse variation.

but least 5 examples
direct variation :-A car runs x hour with speed 60 m/h --> Distance y = 60x
He buys x bricks that cost $1.50 each: The cost y = 1,50x
The tree grows x months by 1/2 meter each month -->
Growth: y = 1/2 x
