Solution :: Brain Teaser :: Can You Solve the Logic Puzzle?

Here we had to apply the Formula -->

x² + y²- ( x + y )

Lets us solve the first row:: 10 + 11 = 200

x² + y²- ( x + y ) = 10 square + 11 square - (10 + 11) = 100 + 121 - 21 = 221 - 21 = 200

Now lets take the last row in question which is :: 16 + 17 = ?

x² + y²- ( x + y ) = 16 square + 17 square - (16 + 17) = 256 + 289 - 33 = 545 - 33 = 512

Finally the answer to the puzzle was:: 512

I guess this was a tuff problem to solve and we had just two entries for the same. And only one entry provided the right answer..

Adding the two numbers then multiplying it with the number placed in the unit's place of the second number.

Thank you very much.

This one looks like
(left + right) * (right % 10)
(14 + 15) * (15 % 10)
= 29 * 5
= 145
