A puzzle for your amusement…. This is the way I received it… there is a logic to it…

They say only people with an IQ of 120 and over are able to figure this



2 + 3 = 10

7 + 2 = 63

6 + 5 = 66

8 + 4 = 96


9 + 7 =

    The answer is 144.Here's how I did this…2+3 is 5. Now multiply 2 with 5 which gives 10.7+2 is 9. Multiply 7 with 9 which gives 63.6+5 is 11. Multiply 6 with 11 which gives 66.So, similarly, 9+7=16. Now multiply 9 with 16 which gives 144.

    Wow..I recall my engineering days when all sorts of series and recursions where given to find a logic – Fibonacci being the most popular. 2 readers have already commented the answers. Its 144. It took me 5 minutes to guess. I am not sure if 5 mins is a long time. :-S


  4. Without looking at the answers I have also calculated it as 144.
