Question
In this age, Peter is three times of Paul's age. In five years, Peter's age will be twice that of Paul's age. What are their current ages?
Solution
Let's denote Peter's current age as P and Paul's current age as Q.
From the problem, we have two equations:
-
P = 3Q (Peter is three times as old as Paul)
-
P + 5 = 2(Q + 5) (In five years, Peter's age will be twice that of Paul's age)
Now, we can solve these equations step by step:
Step 1: Substitute equation 1) into equation 2):
3Q + 5 = 2(Q + 5)
Step 2: Simplify the equation:
3Q + 5 = 2Q + 10
Step 3: Subtract 2Q from both sides:
Q = 5
Step 4: Substitute Q = 5 into equation 1):
P = 3 * 5 = 15
So, Peter is 15 years old and Paul is 5 years old.
