Given Information:
- 3 years ago, the average age of a family of 5 members was 18 years.
- On the addition of a child, the present average age is still the same.
Let's solve the problem step by step:
Step 1: Find the total age of the family 3 years ago
- 3 years ago, the total age of the family of 5 members = 5 members * 18 years = 90 years
Step 2: Find the total age of the family at present
- Currently, there are 5 members in the family and the average age is still 18 years.
- So, the total age of the family at present = 5 members * 18 years = 90 years
Step 3: Find the total age of the family at present after adding a child
- After adding a child, the total number of family members becomes 6.
- Let the age of the child be x years.
- The total age of the family at present after adding the child = (5 * 18) + x
Step 4: Set up the equation
- According to the given information, the average age of the family remains the same after adding a child.
- Hence, (5 * 18) = (6 * 18 + x) / 6
- Solving this equation, we get x = 6
Therefore, the present age of the child is 6 years.
- 3 years ago, the average age of a family of 5 members was 18 years.
- On the addition of a child, the present average age is still the same.
Let's solve the problem step by step:
Step 1: Find the total age of the family 3 years ago
- 3 years ago, the total age of the family of 5 members = 5 members * 18 years = 90 years
Step 2: Find the total age of the family at present
- Currently, there are 5 members in the family and the average age is still 18 years.
- So, the total age of the family at present = 5 members * 18 years = 90 years
Step 3: Find the total age of the family at present after adding a child
- After adding a child, the total number of family members becomes 6.
- Let the age of the child be x years.
- The total age of the family at present after adding the child = (5 * 18) + x
Step 4: Set up the equation
- According to the given information, the average age of the family remains the same after adding a child.
- Hence, (5 * 18) = (6 * 18 + x) / 6
- Solving this equation, we get x = 6
Therefore, the present age of the child is 6 years.
