Can You Solve This Math Puzzle? When I Was 4 Years Old My Brother Was Half Of My Age. Now I’m 18, How Old Is My Brother?

Math puzzles are not always just purely numbers. Sometimes, they give all the information you need in words, like in this case. Today’s brainteaser has proven to be quite tricky for a lot of people. However, do you think you are part of the elite that can solve it?

Siblings always like reminding each other about who has the authority, and the closer their age is, the more it happens. That argument also extends to who their parents love the most: whether it’s the older or the younger one. Needless to say that the fight seldom ends.

But, this puzzle does have a solution! It’s time to warm-up your brain during this holiday season because you might need to do some simple mathematics.

The Puzzle

Here is the puzzle:

You might be wondering how we can possibly figure that out from that sentence. But all the information is right there in the question. Try and read it closer, and think of all that you get to know.

Now, try to solve it! We have the answer waiting for you below.

The Solution

So, for the solution, we start with the first part: “when I was 4 years old, my brother was half my age.” This means that their brother was 2 (half of 4) years old when the person was 4 years old. This also means that their younger brother is younger by 2 years.

Then we take on the second part where we have to find out their brother’s age when they are 18. Since we know that the younger brother is 2 years younger, that means they are (18-2=) 16 years old.

And that is the answer: 16 years!

So did you manage to solve it on your own? How much time did it take you? The trick lies in figuring out everything the question is saying to you. Be sure to share it far and wide if you liked it.
