Solution:

The given question can be solved very easily as shown below.

Given that,

In a family, there are 3 fathers, 3 sons, 2 grandsons, and 1 great-grandson.

Top Branch: 3 Fathers

1st Middle branch: 3 Sons

2nd Middle branch: 2 Grandsons

Bottom branch: 1 Great-grandson

⇒ In the top branch at least 1 father is married because sons are present and to keep it a minimum let us assume only 1 father is married ⇒ 1 wife is required.

⇒ In the 1st Middle branch, at least 1 son must be married because there are grandsons in the next branch ⇒ 1 wife should be present.

⇒ In the 2nd Middle branch, at least 1 grandson must be married because there are great-grandsons in the next branch ⇒ 1 wife should be present.

So 3 more females should be present to complete the family.

Therefore '3' members are required to form a family.
