Question

Mr B is now twice as old as his younger brother. Eight years ago he was three times as old as his younger brother was then. How old is the younger brother now?

Answer 1

M = 2y

(M-8) = 3(y-8)

Substitute 2y for M in the second equation and solve for y.

Answer 2

2y-8=3y-24

24-8=3y-2y
16=y
Therefore Younger brother is 16 years

Oh, I see we have an age conundrum here! Let me clown around with the numbers for a moment.

Let's use the younger brother's age as a variable, shall we? Suppose the younger brother's age is "x" years old.

According to the information given, Mr. B is now twice as old as his younger brother, so we can say Mr. B's age is 2x.

Now, eight years ago, Mr. B was three times as old as his younger brother was then. So, eight years ago, Mr. B's age was (2x - 8), and his younger brother's age was (x - 8).

According to the equation, (2x - 8) = 3(x - 8). Now it's time to clown around with some math tricks.

Let's solve this equation:
2x - 8 = 3x - 24

Subtracting 2x from both sides gives us:
-8 = x - 24

Adding 24 to both sides gives us:
16 = x

So, the younger brother is 16 years old now! But always remember, age is just a number, and it's never too late to join the circus! 🎪

To find the age of the younger brother now, let's first assign variables to the ages of Mr. B and his younger brother. Let's say the younger brother's age is "x" years.

According to the given information, Mr. B is now twice as old as his younger brother. So, Mr. B's age is 2 times the age of his younger brother. Therefore, Mr. B's age is "2x" years.

Eight years ago, Mr. B was three times as old as his younger brother was at that time. This means that 8 years ago, Mr. B's age was three times the age of his younger brother. At that time, his younger brother's age was "x - 8" years.

Using this information, we can set up an equation:

2x - 8 = 3(x - 8)

Now let's solve this equation to find the value of "x":

2x - 8 = 3x - 24
2x - 3x = -24 + 8
-x = -16

Dividing both sides by -1, we have:

x = 16

Therefore, the younger brother is currently 16 years old.
