2) What is the position of “02334” in step IV?
A. Second from the left end
B. Fifth from the right end
C. Fourth from the right end
D. Fifth from the left end
E. None of the above
Sol: Step 1: The unit digit of the square value of each digit of the number is replaced by the original
digit. For example–>92=81–>1 is a unit digit that replaced the number 9. In the case of one digit
square value, then the digit is replaced by its square value.
Step 2: The odd digits are subtracted by 1 and even digits are divided by 2. Zero will remain as
it is.
Step 3: ‘1’ is added to the odd positioned digits (from the left end) and ‘1’ is subtracted from the
even positioned digits (from the left end). If 1 is added to zero it will be 1 but if 1 is subtracted from 0 it will be zero.
Step4: The middle two digits are added, if the result is two-digit again it will be added within the
number and all digits are arranged in ascending order within the number from the left end.
For example ->409730 ->9+7=16 ->1+6=7 ->00347
Step5: The difference between the sum of even numbers and the sum of odd numbers.
