Answer : 7/8
Detailed Explanation:
Each of the three numbers could either be even or odd.
Total number of combinations of such numbers = 2^3 = 8
There is only one combination where multiple of 3 numbers would be odd is when K1, K2 and K3 all are Odd numbers.
For rest all 7 combinations the multiple of 3 number would always be even.
Hence probability = 7/8.

Key Learning:
When any number is multiplied by an even number, the result is always a even number

Tips For CAT/MBAJune 29, 2011 at 11:04 AM
Hi Jagdeep,

You could start with 2 hours of CAT preparation per day.

As you have sufficient time left for the exam, you should plan your preparation in best possbile way. The fist thing which you should do is analyze yourself so as to find your strength & weaknesses. How to find your strength & weaknesses
1.Simply pick up a past years CAT exam paper:
Past Year Papers
Download Past Year Papers for MBA Exams
2. Attempt as many questions as you can without putting the time limit in one go (say you sit for 4 hours read all the questions & attempt which ever you are confident of.....don't make any blind guess for any of the questions.....feel free to make calculated guess in verbal section :) ).
3. Write down your overall score, along with sectional score
4. Repeat step 1-3 for 2 more Past Year CAT Papers

With your consolidated scores for two to three attempts of Mock CAT tests, you would be able find which section is your strength and which one is your weakness.
Please Remember: Initially when you write any mock tests with same time limit as actual CAT, your scores would be quite low as you are yet to master the time
management. So don't panic, slowly with time & with your preparation in progress your score will rise progressively.

Once you have finished analyzing yourself, you need to start working on wekanesses & mastering your strengths. Please refer below link to find out which books/study materials you should refer:
List of books & study materials for MBA Preparation

Would recommend you to focus on spoken english as well, please form a group within your friend circle and have mock Extempore/ GDs/ Interviews/ Debates. This will not only help you in your MBA preparation but also for job interviews & will surely help in your overall personality/career development.
I hope you should be able to organise such a session for half an hour everyday within your college campus or hostel.
