You have 'IQ of Albert Einstein' if you can solve tricky maths equation in 15 seconds – The Mirror
You’ll need the ‘IQ of Albert Einstein’ if you want to be able to solve this tricky maths equation in under 15 seconds – do you think you have what it takes to answer it?
You'll need a genius-level IQ if you want to work out this maths equation.
Let's face it, maths isn't a subject many of us enjoyed at school, and if you don't need to use it on a day-to-day basis for your job, you've probably forgotten a lot of the important things you were taught about algebra and long division. But refreshing your memory and trying to solve maths puzzles can be a great way to boost your cognitive function and give your brain a workout. So if you're looking to exercise your mind, why not give this brain teaser a try?
Take a look at the picture above. You'll see three sums with their respective solutions, but there's one thing wrong with the picture – all the numbers in the sum have been replaced by fruits. There's then a fourth sum at the bottom that doesn't have a solution, and it's your job to work that answer out.
The puzzle is essentially an algebra one, as you could replace the fruits with letters in order to break things down into sums that might look more familiar to you. For example, the top sum reads: Apple + Apple + Apple = 30. This can also be written as A + A + A = 30, which is the same as 3A = 30. To work this sum out, all you need to do is divide 30 by 3 to give you the value of A, which makes A – and by extension, the apple – equal to 10.
Now that you know that Apple = 10, you can use that information to work out the other sums where apples are present. In the second sum, one apple plus two bunches of bananas is 18. If you know the apple is worth 10, the banana bunches must be 8 each, making one banana bunch equal to 4.
With all that knowledge, can you work out the rest of the puzzle? According to Jagran Josh it takes an "IQ of Albert Einstein" to be able to work out the answer in just 15 seconds – so you better hurry up if you want to consider yourself a genius.
The answer to the final question is 14 – did you get it right?
In the second-to-last question, one bunch of bananas minus two cherries is 2. We know that the bananas are worth 4, so the cherries must be worth 2 together, making one cherry worth 1. You can then use this information to work out the final equation – but be careful because there's a key piece of information you'll need to be aware of.
The bunch of bananas in the final sum only has three bananas in it, whereas the ones pictured in earlier sums had four. If four bananas are equal to four, then it can be assumed that each banana is worth one. This means the final sum is: 1 + 10 + 3, making the final answer 14.
