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?
M = 2y
(M-8) = 3(y-8)
Substitute 2y for M in the second equation and solve for y.
2y-8=3y-24
24-8=3y-2y
16=y
Therefore Younger brother is 16 years
SORRY MISTAKE, PLEASE DISCARD.
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.
