Answer – c) 16 years Explanation : At the time of marriage sum of the age of husband and wife = 44 years.
After three years, total age of the family = 44 + 3+ 3+ 1 = 51 years.
At the time of child birth, age of family = 51 -1-1-1 = 48 years.
So average age = 48/3 = 16 years
After three years, total age of the family = 44 + 3+ 3+ 1 = 51 years.
At the time of child birth, age of family = 51 -1-1-1 = 48 years.
So average age = 48/3 = 16 years

To find the average age of the family of three at the time of birth of the child, we need to determine the sum of their ages and divide it by the number of people in the family.
Given information:
- The average age of a husband and wife at the time of marriage is 22 years.
- After 3 years, they have a one-year-old child.
Let's break down the problem and solve it step by step.
Step 1: Determine the sum of ages at the time of marriage
The average age of the husband and wife at the time of marriage is 22 years. Since there are two people in the family at this time, the sum of their ages would be 22 x 2 = 44 years.
Step 2: Calculate the sum of ages after 3 years
After 3 years, the child is one year old. This means that the sum of the husband and wife's ages would increase by 3 each (3 years have passed). So the new sum of ages would be 44 + 3 + 3 = 50 years.
Step 3: Determine the average age at the time of birth of the child
Now that we have the sum of ages after 3 years, we need to divide it by the number of people in the family at that time, which is 3 (husband, wife, and child). Therefore, the average age would be 50 / 3 = 16 years.
So, the average age of the family of three at the time of birth of the child is 16 years. Therefore, the correct answer is option C.
