Study the following information carefully and answer the questions given below : In a certain code language, ‘prepare for your exam’ is written as xn nt oz wl’. ‘hard work for prepare’ is written as ‘nt ml oz tk’ ‘prepare your study well ‘ is written as ‘sd jk nt xn’ ‘work well best result’ is written as ‘ds lu jk ml’ (All the codes are two lettered codes only) Which of the following may represent ‘exam is hard’ ?

Explanation

The common word in the second and third statements is 'prepare' coded as = 'nt' Also, the common word in the first two statements (except prepare) is 'for' coded as = 'oz' Similarly, common word in first and third statements is 'your' coded as = 'xn' => Only word left in 1st statement is 'exam' coded as = 'wl' Also, common word in second and last statements is 'work' coded as = 'ml' => Only word left in 2nd statement is 'hard' coded as = 'tk' Similarly, common word in last two statements is 'well' coded as = 'jk' => Only word left in 3rd statements is 'study' coded as = 'sd' Also, in 4th statement, codes for 'best' or 'result' = either 'ds' or 'lu' Thus, ‘exam is hard’ may be represented by = tk zr wl => Ans - (D)
