The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?
Answer: 4 years
Explanation
Step 1: Let's denote the age of the youngest child as x.
The ages of the 5 children will be x, x + 3, x + 6, x + 9, and x + 12.
Step 2: Calculate the sum of their ages.
x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
Step 3: Simplify the equation.
5x + 30 = 50
Step 4: Solve for x.
5x = 20
x = 4
