Solution along with Tips

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

  2. 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:

    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.

    thanks for reading this

    1. Dear Diksha,

      In general people don't do MBA for joining Govt. Jobs. With your dream to do Govt. job I could suggest you following:
      1. Don't do MBA instead do M.Com and try for Banking Jobs
      2. Try for CA
      3. Do MBA in Rural Management from colleges like IRMA or power management.

      Have a nice day...

      One request:
      We desperately require your support to keep this free blog running, please do support us by sharing this site with all your friends, online MBA groups,

      Keep Writing!!!

      All the best!
