If Z = 52 and ACT = 48, then BAT will be equal to
Answer: D
Correct answer: 46
Each letter is worth twice its position in the alphabet, as Z = 26 × 2 = 52 confirms. Checking against the second clue, ACT = 1 + 3 + 20 = 24, and 24 × 2 = 48. So BAT = 2 + 1 + 20 = 23, and \[ 23 \times 2 = 46. \]

If JOSEPH is coded as FKOALD, then GEORGE will be coded as
Answer: A
Correct answer: CAKNCA
Every letter moves four places back: J→F, O→K, S→O, E→A, P→L, H→D. GEORGE therefore gives G→C, E→A, O→K, R→N, G→C, E→A, that is CAKNCA. Since GEORGE has G and E twice each, the code must repeat C and A in the same places, which rules out three of the four options at a glance.

If in a code language, COULD is written as BNTKC and MARGIN is written as LZQFHM, how will MOULDING be written in that code ?
Answer: C
Correct answer: LNTKCHMF
Both examples use the same rule, a shift of one place back: COULD gives BNTKC and MARGIN gives LZQFHM. MOULDING therefore becomes M→L, O→N, U→T, L→K, D→C, I→H, N→M, G→F. Two examples are given precisely so the rule can be confirmed rather than guessed from one.

In a certain code language MONKEY is written as LNMJDX. How will TIGER be written in that code ?
Answer: C
Correct answer: SHFDQ
Each letter of the original is replaced by the letter immediately before it in the alphabet: M becomes L, O becomes N, and so on throughout.
Applying the same shift to TIGER gives S, H, F, D, Q.

In a certain code, MONKEY is written as XDJMNL. How is TIGER written in that code ?
Answer: A
Correct answer: QDFHS
Two operations are combined. Reverse MONKEY to get YEKNOM, then move each letter one place back: Y→X, E→D, K→J, N→M, O→N, M→L, giving XDJMNL. TIGER reversed is REGIT, and stepping each back gives R→Q, E→D, G→F, I→H, T→S, so the code is QDFHS.

If BOMBAY is written as MYMYMY, how will TAMIL NADU be written in that code ?
Answer: B
Correct answer: MNUMNUMNU
The code is built from every third letter. BOMBAY has six letters, and taking the third and the sixth gives M and Y, written three times over as MYMYMY. TAMILNADU has nine, so the third, sixth and ninth are M, N and U, and the code is MNU repeated three times.
