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.
