Just like we exercise our body by going to the gym and eating healthily, we should also exercise our brain.

While our brain can’t lift weights or do squats, mind-tasking activities such as math puzzles and riddles have been proven to be beneficial. Today we shall be taking on a math puzzle.

Here is the question: When I was 4 years old my brother was half of my age. Now I’m 18, how old is my brother?

While you might want to look at this task as just riddle, it also involves some math operations. It is essential to know that math puzzles come in different forms.

It can be in the form of an equation that requires you to use the right order of operation, or in the format of a word problem just like the question above.

This puzzle might prove tricky, but if you pay attention to the clue in the statement, you’ll realize it’s pretty straightforward.

If you’re still struggling with coming up with an answer, let’s analyze the question. The first statement reads, ‘when I was 4 years old my brother was half my age.’

First, it’s important to find out what the brother’s actual age was. So, half of four is simply 4 divided by 2 which gives us 2.

This means the speaker is two years older than his or her brother. Now, to the other half of the sentence which reads: ‘Now I’m 18, how old is my brother?’

If we figured out that the age difference between them is 2 years, then his brother’s present age will be 18-2 which is 16!

If you got 9, that means you fell for the trap and divided 18 by 2.

Nevertheless, don’t beat yourself up! Keep solving more problems like this, and you’ll be a pro in no time.
