Correct Answer: C. 872 act 741 end yolk nest 316 508
Step I: The largest number is placed on the first position.
Step II: The first word as per the alphabetical order is placed on the second position.
Step III: The second largest number is placed on the third position.
These steps are repeated until all the numbers are arranged in the descending order and all the words are
arranged in the alphabetical order.
In the next step, the difference of square of middle digit and last digit of the number is written instead of the
nu mber itself.
Then, the number representing the difference of the first and second alphabet of the word is written. Example:
bolt -> b=2, o=15 So, 15-2=13
Then, first half of the series is arranged in descending order and next half of the series is arranged in ascending
order.
