Solutions

Solution (1-5):
In step I, a number obtained by subtracting 2 from 1st digit of each number is written ahead of each number of the given input.
In step II, last digit of each number of step I is written just after first digit of the number, i.e., if a number let’s say 189 given in step I, then in step II it will become 1989.
In step III, first arrange all the numbers in ascending order from left, then interchange 1st digit with 2nd digit and 3rd digit with 4th digit in each number.
In step IV: Sum of 1st and 3rd digit of each number is written ahead of each number given in step III.
In step V: Sum of 1st three digits written in front of the sum of the remaining digits of each number of step IV.

Solution (6-10):
Step I: All the numbers are multiplied by 3.
Step II: The first and the last digit of the number are added and then the sum is multiplied by the second digit.
Step III: All the numbers are divided by 2.
Step IV: The absolute difference of 1st and 2nd number is written. Similarly, absolute difference of 2nd and 3rd number is written. This process is done for the remaining pairs of numbers.
Step V: All numbers are arranged in ascending order from left to right.
