Title: "Family Age Calculation"

Objective: The objective of this exercise is to practice calculating the average age of family members and performing basic arithmetic operations with their ages.

Instructions:

  1. Gather information about the ages of family members, including parents, siblings, and yourself. Ensure you have at least four family members to work with.
  2. Write down the ages of each family member in a list.
  3. Calculate the sum of all the ages in the list.
  4. Divide the sum by the total number of family members to find the average age.
  5. Now, imagine that each family member's age increases by 5 years.
  6. Recalculate the sum and average age using the updated ages.
  7. Finally, subtract the average age before the increase from the average age after the increase.
  8. Write down the final result as the answer to the exercise.

Example: Let's consider a family with the following ages:

  • Father: 40 years old
  • Mother: 38 years old
  • Older sibling: 18 years old
  • You: 15 years old
  1. List of ages: [40, 38, 18, 15]
  2. Sum of ages: 40 + 38 + 18 + 15 = 111
  3. Average age: 111 / 4 = 27.75
  4. Increased ages: [45, 43, 23, 20]
  5. Sum of increased ages: 45 + 43 + 23 + 20 = 131
  6. Average age after increase: 131 / 4 = 32.75
  7. Difference in average ages: 32.75 - 27.75 = 5

Answer: The difference in average ages before and after the increase is 5 years.

Note: You can modify the exercise by adding more family members or changing the age increment to make it more challenging.
