Some friend on Facebook shared the following puzzle from http://9gag.com/gag/aWWv2bx?ref=fbp.
I cleaned up the photo a bit for clarity and show it below:
Learning from the Crowd:
If you scroll through the answers offered, we can find many interesting ones that seemingly solve the puzzle. Here are some answers that I find interesting:(If you find any more answers, let me know and I will try to add in here. I did not go through the whole long list).
- You can't just go around asking white people questions designed for an Indian.
- Impossible! 3 odd numbers can never make an even number.
- The question is "can you solve it ?" Answer is "no"
- Read closely and you will see it never stated fill in ALL the boxes... 15+15+[ ]=30
- 3! + 15 + 9 = 30 (3! is 3 factorial, which is 3x2x1=6)
- Nobody said we could not used the decimal point: 7.5+7.5+15=30 or 15.3 + 13.7 + 1 =30
- Put in two numbers in a box as: [1+3] + [5+7] + 13 = 30
The real world will be demanding you to solve such seemingly difficult problem. So what and how should you do?
Abstract one level higher from the above answers provided, I have derive the follow creative rules or principles from the answers, in corresponding order, for better life or for your problem solving:
- Laugh at it and ignore it. Be happy.
- Say it is impossible and do something else.
- Examine the situation, you may have misunderstood or misread it.
- Examine the situation, they are not demanding too much but you have.
- Look at it with a different perspective. Take a helicopter view.
- Solve it with better technology and skills.
