a) LSEUOAUMM
b) AUUCOSLMM
c) AUEUOSEMM
d) SLUEOAUMM

Explanation: Let us label the letters of the given word from 1 to 9. Then, the code contains the letters of the word in the order 6, 4, 7, 3, 5, 2, 8, 1, 9.
Thus we have :
MAUSOLEUM => LSEUOAUMM
123456789 => 647352819

3. In a certain code language, CREATIVE is written as BDSBFUJS. How is TRIANGLE written in that code?
a) BHSSFKHM
b) BHSSMHHF

Explanation: The letters in the first half and second half of the word are written n the reverse order and then in the group of letters so obtained, the first, third, fifth and seventh letters are each moved one step forward while the second, fourth, sixth and eighth letters are each moved one step backward to get the code.
Thus, we have :
TRIANGLE => TRIA/NGLE => AIRT/ELGN => BHSSFKHM.

4. In a certain code language, OMNIPRESENT is written as QJONPTSMDRD. How is CREDIBILITY written in that code?
