Given, the word COMPATIBLE is coded as BQNPDDKAHS.
First, we need to find the pattern among the coded letters with the original word. COMPATIBLE contains ten letters and its corresponding coded word BQNPDDKAHS also contains the same number of letters. So, each letter has its own code.
Logic: The word COMPATIBLE is to be divided into two equal parts and both parts are to be reversed separately. Then, each letter which are in the first part is shifted ahead to one place, and each letter in the second part is shifted one place back to its original place.
COMPATIBLE => COMPA/TIBLE => APMOC/ELBIT => BQNPD/DKAHS => BQNPDDKAHS

Similarly, for the word STABILISED,
STABILISED => STABI/LISED => IBATS/DESIL => JCBUT/CDRHK => JCBUTCDRHK
Hence, the coded word for STABILISED is JCBUTCDRHK.
Hence, "JCBUTCDRHK" is the correct answer.

d): The terms of series are (10 * 11) (12 * 13) (14 * 15) (16 * 17) (18 * 19) or 110 + 46 -> 156 + 54 -> 21 62 -> 272 + 70 342.

(d): 6, 19, 60, 189, ?, 1863 6 * 3 + 1 594 * 3 + 81 19 * 3 + 3 60 * 3 + 9 189 * 3 + 27

The letters in the first half and second half of the word are written in the reverse order and then each letter of the group so obtained is moved one step forward to get the code.

Thus, we have
COVALENT- COVA / LENT- AVOC / TNEL
→
BWPD / UOFM
and
FORM- FO / RM- OF / MR
→
PG / NS

In the same way,
SILVER– SIL / VER– LIS / REV
→
MJT / SFW
Hence, the correct answer is MJTSFW.

A man turns 90∘ clockwise and 135∘ anti clockwise. Thus, in all man turns 40∘anti-clockwise. Hence, the man now faces west.
