Question

    In a certain code language, '2, 4, 6' means 'object for

    required'; '6, 3, 5, 2' means 'circular for motion required' and '3, 7, 4, 1' means 'object small motion mass'. Which of the following means 'circular' in that language?
    A 3 Correct Answer Incorrect Answer
    B 6 Correct Answer Incorrect Answer
    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’.
