    In a certain code, BREAKTHROUGH is written as EAOUHRBRGHKT. How is DISTRIBUTION written in that code?

    A) TISTBUONDIRI 

    B)                    STTIBUONRIDI

    C) STTIBUDIONRI 

    D)       RISTTIBUDION

    E) None of these

    Correct Answer: C

    Solution :

    Explanation Option [c] is correct. let us divide the letters of the given word into pairs and label these pairs from 1 to 6. \[\frac{BR}{1}\] \[\frac{EA}{1}\] \[\frac{KT}{3}\] \[\frac{HR}{4}\] \[\frac{OU}{5}\] \[\frac{GH}{6}\] Clearly, the code contains these pairs arranged in the order 2, 5, 4, 1, 6, 3. Dividing the letters of the word DISTRIBUTION in pairs, we have: \[\frac{DI}{1}\]  \[\frac{ST}{1}\] \[\frac{SI}{2}\]  \[\frac{RI}{3}\]  \[\frac{BU}{4}\] \[\frac{TI}{5}\]  \[\frac{ON}{6}\] Arranging these in the order 2, 5, 4, 1, 6, 3, we get the required code i.e. STTIBUDIONRI. Hence, the answer is [c].
