Solutions (1-5):
For step-I, both the digits of 1st block is written as, Ist digit of block-1 of the Input is multiplied with 2nd digit of block-4 of the Input same as 2nddigit of block-1 is multiplied with 1st digit of block-4. This process is same for Block-2 and Block-3 in step-1.
For step-II, All 1st digit of each block is added and that sum is written in 1st block and all 2nd digit of each block is added and that sum is written as 2nd block.
For step-III, Half of the addition of 1st and 2nd digit of each block.
For Step- IV, Difference of both numbers of Step-3.

Q10. How many steps are required to perform the output?
(a) VII
(b) V
(c) III
(d) VI
(e) IV
Solutions (6-10):
Sol. In this new pattern coding decoding question only one word and one number is arranged in each step. Let us understand the logic behind it- In each step the words and the numbers both are arranged from the left end.
For words- Words are arranged according to their 1st letter in such a way that the letter which has highest place value according to alphabetical series is arranged first from left end and each letter of each word is replaced by its second succeeding letter according to alphabetical series and same will be followed in each step.
For numbers- Numbers are arranged in descending order from left end in such a way that each number is multiplied by two.
