Question
How is ‘teacher’ written in a code
language? The given question is followed by information in two statements. You have to find out which statement follows the information and mark your answer accordingly. Statements: I. 'I am teacher' is written as 'op ne pa' and 'Happy teacher day' is written as 'pa ka jh'. II. 'mother is best teacher' is written as 'xy lm pa hi' and 'My mother is teacher' is written as 'hi pa cr lm'.Solution
From statement I: I am teacher is written as 'op ne pa' Happy teacher day is written as 'pa ka jh' From the above, code for 'teacher' is 'pa'. Hence, statement I is sufficient to answer the question. From statement II: Mother is best teacher is written as 'xy lm pa hi' My mother is teacher is written as 'hi pa cr lm' From the above, ' we cannot determine the code for 'Teacher' a s two words ‘Teacher’ and ‘Mother’ are common in both the statements. So, statement II is not sufficient to answer the question. Hence, the data in statement I alone is sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
