TopNewestAs stated, this is not a magic square. But assuming it's one of those "brain "teaser" tests", here's a solution that I see perfectly valid while not helping you at all:

The third number in each row is the minimum of the other two numbers in the row, multiplied by their sum.

By this, the question mark is either \(64\) or \(\dfrac{-1-3\sqrt{29}}{2}\). Neither is among the given choices.

The above simply states that doing such questions just wastes your time, because there are infinitely many interpretations possible, and a bunch of "plausible" interpretations. – Ivan Koswara · 3 years, 7 months ago

Thank you Ivan for correcting me! The same question appeared in an examination which I gave. Can you come up with a solution among the four options?Log in to reply

Well guys, I think Rashmi gave the most accurate answer of this problem. Thanks a lot Rashmi. Nice try Ivan, Bhargav and Likhita! – Vinayak Verma · 3 years, 7 months ago

This is not a magic square ! The sum of the numbers in each column and row must be same in a Magic square – Rashmi B K · 3 years, 7 months ago

Thank You for correcting my knowledge about the magic squares. Well, did you come up with any more answers?Log in to reply

\(8+2 + 10 = 20\)

\(4+6+ 30 = 40\)

\(x+1+ 50 = 65\)

we end up \(x=14\) – Rashmi B K · 3 years, 7 months ago

I think you are somewhat correct as you got the most possibly correct answer. Thanks a ton. Cheers!Log in to reply

I think the logic used here ,to get one of the options given as the answer is: \(20 - (8 \times 2)=4=2^{2}\) \(40 - (4 \times 6)=16=4^{2}\). That is, the above pattern is followed to get a

perfect square. So,putting the various values we get,\(16\) as our required answer as \(65 - (1 \times 16)=49=7^{2}\), which is a perfect square. Hope that helps! – Bhargav Das · 3 years, 7 months agoLog in to reply

I tried this logic of yours many a times but I don't think it is the most accurate answer. Nonetheless, nice try Bhargav. I think Rashmi gave the most accurate answer. Go check hers!Log in to reply

In the examination, the options enlisted were only these. I am sure the answer is one of the above options which I gave. Thank You for giving an answer. Can you provide a solution also?Log in to reply

Please I want the answer asap. If possible please provide me the solution. – Vinayak Verma · 3 years, 7 months ago
