To succeed in life, you must "think outside the box." This cliché is used to describe creative, non-standard approaches to problem solving. But how does one learn to "think outside the box?" Unfortunately, there is no simple answer. Author Kiran Srinivas believes that you can significantly improve your thinking abilities, and his book Brain Teasers will force you to think in ways you never have before. By sheer practice, you can increase your ability to think creatively.Many of the puzzles in this book will take hours, if not days, to solve, but be encouraged, a middle-school education is sufficient to answer almost all of the puzzles. There are many interview puzzles, and if you plan to interview at an investment bank, consulting firm, high-tech firm, or in any other related field, absorb what Brain Teasers has to offer, as it can be the deciding factor in getting that offer.

5.0 out of 5 stars
Dangerously entertaining,
By Jan Harelson (Ft.lauderdale, FL) - See all my reviews
This review is from: Brain Teasers (Paperback)
Wow! This book is so much fun. But I am warning you that it is also very addictive so make sure that you have the time and patience. I would love to see some follow-ups since I'm almost all the way through. Thanks!!!

Mistake in Teaser #18,
By
Amazon Verified Purchase(What's this?)
This review is from: Brain Teasers (Paperback)
The answer to Brain Teaser #18 is incorrect. !Spoiler Alert!
The answer should be 27000001. The problem is that all the digital sums are not 55 as the answer key suggests. For example consider the pair: (10 - 999,990) Here the digital sum is 46! In fact if you break it down only 450000 of the sums are 55, 45000 of the sums are 46, 4500 are 37, 450 are 28, 45 are 19 and 4 are 10. So the method of solution is not viable because the above would be difficult to figure out (I used a computer). Rather the proper analysis is to show that each place value contributes 100000 of each number for 1-999,999 (e.g, there are 100000 1's in the ones column, 100000 1's in the tens column, and so on) So you get 600000 * 1 + 600000 *2 ... 600000 *9 = 600000 (1+2+3+4+5+6+7+8+9) = 600000 * 45 = 27,000,000 But you need to add 1 for 1,000,000 So the final answer is 27000001 This is also verified by the following Mathematica brute force program: digitalSum[x_] := Total[Flatten[IntegerDigits[Table[i,{i,1,x}]]]] digitalSum[1000000] 27000001 Don't know of any other mistakes and otherwise the book is excellent!!

Amazon Verified Purchase(What's this?)
This review is from: Brain Teasers (Paperback)
The problem with many "brain teaser" books is that they all have many of the same questions. That is not the case with this book. The questions in this book are challenging and fun. Makes for a great book to keep at the office to break up the monotony of the work day.
