Question
elect the correct answerThe sum of ages of 5 children born at the intervals of 3 years each is 50 years. Find out the age of the youngest child?Options4 years5 years6 years3 years
Solution
Let's denote the age of the youngest child as x. Then the ages of the other children would be x+3, x+6, x+9, and x+12.
According to the problem, the sum of their ages is 50. So we can write the equation:
x + (x+3) + (x+6) + (x+9) + (x+12) = 50
Solving this equation will give us the age of the youngest child.
First, simplify the left side of the equation:
5x + 30 = 50
Then, subtract 30 from both sides of the equation:
5x = 20
Finally, divide both sides of the equation by 5:
x = 4
So, the age of the youngest child is 4 years.
