Solutions

Solutions (1-5):
Sol. In Step 1: The first three digits in all the numbers from the left end, are written in reverse order with in the number. No change is made to the remaining digits.
Ex-(64533) will be arranged as (54633).
In Step II: The numbers are arranged in descending order from extreme left end (according to the sum of the digits). (Number with the highest sum of digits will be arranged at extreme left end and the number with the 2nd highest sum of digits will be arranged after the 1st number and so on).
In Step III: The product of 1st and last digit from the left end of the number is written (from the left end) at the starting of each number, followed by the remaining digits in the same sequence to form a five-digit number. Ex- (85794) will be arranged as (32579).
(8 × 4) = 32, and (579) will be written in same sequence, so (32579).
In Step IV: The sum of first three digits from the left end is written at the left end of each number within the number, followed by remaining digits in the same sequence to form a four-digit number. Ex- (32579) will be arranged as (1079).
(3+2+5) = 10, and (79) will be written in same sequence, so (1079).
In Step V: All the numbers are arranged in ascending order from the extreme left end.
In Step VI: All the digits of each number are arranged in descending order within the number.
