    hese question are not meant to solve completely and find the exact logic. These questions are generally asked in competitive examination. It may take 20 to 30 mins to get the logic and in that case, you will be able to attempt this single question. What the examiner expect is Strong Observation. Then only, you can solve in 30 to 45 seconds.

    KFDN Trick for such problem: Observe, Verify and Implement

    Coming to question, a common observation in 1st circle is the largest number in circle 1 is 2184, which is written in 1st quadrant.

    Observation: Sum of remaining quadrant is 4+8+1 ie 13. Also, difference of 2nd and 4th quadrant is 3. 2184 is factor of both 13 & 3

    Now, verify the same in 2nd circle. 5+6+2 = 13 and difference of 2nd and last quadrant is 3. So, largest number 2184 is factor of 13 as well as 3.
    By same logic in circle 3, 8+4+5= 17 and difference between 2nd and 4th quadrant is 3. So, answer must be multiple of 17 and 3. Only option is 4896. So, it will be answer.

    4+8+1 = 13
    13^3 – 13 =2184

    5+6+2 = 13

    13^3 – 13 =2184

    so 8+4+5 = 17

    17^3 – 17 = 4896

    Answer is 4896
