    The Square Of Mark’s Age 3 Years Ago Is 6 Times The Age He Will Be In 9 Years. What Is His Age Now?

    Math puzzles are a great way to test your logical thinking and problem-solving skills. They can also be a lot of fun if you know the right approach. One such puzzle is the square of Mark’s age 3 years ago being 6 times the age he will be in 9 years. So, what is Mark’s age now? In this blog post, we will walk you through this mathematical conundrum, step-by-step. We’ll show you how to dissect and solve it using simple algebra and basic arithmetic. By the end of it, you should have an answer to this puzzle – as well as an insight into how to tackle similar problems in the future.

    What is the square of Mark’s age 3 years ago?

    Mark is currently 9 years old. 3 years ago, he was 6 years old. The square of Mark’s age 3 years ago is 36. In 3 years, Mark will be 12 years old. The square of his age then will be 144.

    What is the age he will be in 9 years?

    In 9 years, Mark will be 36 years old. The square of Mark’s age years ago is times the age he will be in 9 years. So, if we solve for x, we get:

    x^2 = 36

    x = 6

    Therefore, Mark is currently 6 years old.

    How to calculate his age now

    To calculate Mark’s age now, we need to first determine the value of x in the equation. We can do this by solving for x:

    x = Mark’s age now

    Plugging in the known values, we get:

    x = (24 years ago)^2 / (4 years from now)

    x = 576 / 4

    x = 144

    Therefore, Mark’s age now is 144 years old.

    Conclusion

    We have successfully solved the age equation and found that Mark’s current age is 12 years old. Although this might seem like a rather tricky problem, it can actually be solved relatively quickly with a bit of algebraic manipulation. By isolating one of the variables and then using some simple calculations, we were able to arrive at the right answer in no time. In our increasingly digitalized world, understanding basic algebra is an invaluable skill that every person should have in their arsenal.

    Have you ever been asked a math question like this? It can seem difficult to understand, but by breaking it down step-by-step, you can easily solve it!

    Let’s start by looking at the question: The square of Mark’s age 3 years ago is 6 times the age he will be in 9 years. What is his age now?

    To solve this problem, we need to figure out Mark’s age 3 years ago and the age he will be in 9 years.

    Let’s start by figuring out Mark’s age 3 years ago. To do this, we can subtract 3 years from his current age. For example, if Mark is currently 15 years old, then 3 years ago he would have been 12 years old.

    Now, let’s figure out the age he will be in 9 years. To do this, we can add 9 years to his current age. For example, if Mark is currently 15 years old, then in 9 years he will be 24 years old.

    Now that we know Mark’s age 3 years ago and the age he will be in 9 years, we can solve the problem. We know that the square of Mark’s age 3 years ago is 6 times the age he will be in 9 years. So, if Mark was 12 years old 3 years ago, then the square of 12 would be 144. And if Mark will be 24 years old in 9 years, then 6 times 24 would be 144.

    Therefore, Mark’s age must be 15 years old now.

    It’s not too hard to solve this kind of problem. Just break it down and work through it step-by-step.
