Question
Twenty years hence Ron will be five times as he was 36 years ago, his present age is: Ops: A. 65 years B. 40 years C. 48 years D. 50 years
Solution
Let's denote Ron's present age as X.
According to the problem, twenty years from now, Ron will be five times as old as he was 36 years ago. This can be written as:
X + 20 = 5 * (X - 36)
Solving this equation will give us Ron's present age.
First, distribute the 5 on the right side of the equation:
X + 20 = 5X - 180
Then, subtract X from both sides:
20 = 4X - 180
Next, add 180 to both sides:
200 = 4X
Finally, divide both sides by 4 to solve for X:
X = 50
So, Ron's present age is 50 years old. Therefore, the correct answer is D. 50 years.
