Solutions

Solution (1-5):
Sol.
Step I: The words are arranged in the alphabetical order from the left end
Step II: The letters of the words are arranged in alphabetical order within the word.

Step IV. The words are arranged in reverse alphabetical order from left end.
Step V: The letters of the word are arranged in alphabetical order within the word.

S5. Ans.(a)

Solution (6-10):
Sol. Different logic is applied in each step.
Step I: middle four digits of first number are interchanged by middle four digits of the second number. Similarly, middle four digits of third number are interchanged by middle four digits of the fourth number. This process continues with fifth and sixth number.
Step II: First break the number in two parts: 1st number = first three digits and 2nd number = last three digits of the original number. Then combine both 1st and 2nd number and get the resultant number in step II.
Step III: One is subtracted from the digits which are greater than 5 and 2 is added to the digits which are less than or equal to 5.
Step IV: sum of the digits is written.
Step V: odd numbers are multiplied by 4 whereas even numbers are multiplied by 3
Step VI: we write @, If the digit is odd and we write # if the digit is even.
