Solutions (1-5):
(i) By using the conditions, S sits fourth to the right of M who is facing north side. R sits second to the right of M. There are only two persons sit between S and N who is not an immediate neighbor of M. N is facing north. There are only four persons sit between N and the one who likes green. T likes black sit second to the left of S.
(ii) Q, who likes orange is an immediate neighbour of S and does not face south, so Q can sit either immediate left or right of S. T faces opposite direction to R, who faces same as Q, so R faces north and T faces south.
(iii) O and P facing same direction but opposite to N, so O and P face south. The one who likes grey is an immediate neighbour of the one who likes black, in case 1 N likes grey but in case 2 it will not fix. O sits fourth to the right of the one who likes yellow, from this case 1 will be eliminated because no place is left for O.
(iv) Case 2 will be continued, in case 2 O is an immediate neighbour of M and P likes yellow. N likes grey. The one who likes white is facing north and sits fourth to the right of the one who likes purple, So M likes white and S likes purple. Rest O likes blue.

(b) bag
(c) 37
(d) 58
(e) None of these
Solutions (6-10):
Sol. Students let us understand the Logic behind this Question and let’s understand how to solve it. When we see the each step, then we can find that
The machine rearranges one word and one number in each step simultaneously, words are arranged from left end and numbers are arranged from right end.
(i) In this, words are arranged in decreasing manner according to addition of place value of 1st and 2nd letter of the word.
(ii) Numbers are arranged in decreasing order, first all prime numbers are arranged after that non-prime numbers are arranged.
INPUT: 23 title 37 bag 58 building 36 hello
Step 1: Title 23 bag 58 building 36 hello 37
Step 2: Title building bag 58 36 hello 37 23
Step 3: Title building hello bag 36 37 23 58
Step 4: Title building hello bag 37 23 58 36
