      C 5 Correct Answer Incorrect Answer
      D 2 Correct Answer Incorrect Answer

      Solution

      ‘'2, 4, 6' - 'object for required'……. (i) '6, 3, 5, 2' - 'circular for motion required' ……. (ii) ''3, 7, 4, 1' - 'object small motion mass'….. (iii) From (i) and (ii), code for ‘for required' is either ‘2 or 6’. From (ii) and (iii), code for ‘motion’ is ‘3’. We know the code for ‘for required' and ‘motion’, so from (ii), ‘5’ is the code for 'circular’.
