In a certain code, MOTHER is written as RMOTEH. How is SISTER written in that code?
Answer: B
In MOTHER→RMOTEH: positions are rearranged as 6,1,3,4,5,2. Applying same pattern to SISTER (6 letters): S(6)→R, I(1)→S, S(3)→I, T(4)→S, E(5)→E, R(2)→T = RSISET

PAINT is coded as QCMOU in a certain code. What is the code for GRAIN?
HISTORY is coded as IJTUPSZ. How is MYSTERY coded?
Answer: D
H→I(+1), I→J(+1), S→T(+1), T→U(+1), O→P(+1), R→S(+1), Y→Z(+1). So M→N, Y→Z, S→T, T→U, E→F(no, should be...recalc), R→S, Y→Z gives NZUTFSZ approximately.
Q.11Medium
TEMPLATE is coded by separating vowels and consonants, then rearranging. If vowels (E,A,E) come first, then consonants (T,M,P,L,T), what is the code?
Answer: C
Vowels in order: E, A, E. Consonants in order: T, M, P, L, T. Code: EAETMPLT (8 letters for TEMPLATE-8 letters).
Q.12Medium
In a code, each consonant is replaced by the next consonant and each vowel is replaced by the previous vowel. KNOWLEDGE is coded as?
Answer: C
K→L, N→N, O→A, W→X, L→D, E→A, D→S, G→E. Consonants shift to next consonant, vowels to previous vowel.
Q.13Medium
MUSIC is coded as NZVJD. Which word would be coded as OZYMHF?
Answer: A
Each letter shifts by +1. Reverse code: O→P, Z→L, Y→A, M→N, H→E, F→T. This gives PLANET.
Q.14Medium
BEACON is coded by writing alternate letters backwards: EAO + NCB. How would STATION be coded?
Answer: A
STATION: alternate letters are S-A-I-O and T-T-O-N. Backwards: TAI + NOTS (reversing T-A-T-I-O-N placement).
Q.15Medium
In a code, SPRINT is written as TQSOUT. What is the logic?
Answer: B
SPRINT reversed is TNIRPS. Then S→T, P→Q, R→S, I→O, N→U, T→T (shift +1). Result: TQSOUT.
Q.16Medium
NETWORK is coded by separating consonants and vowels: consonants in reverse, vowels forward. What is the code?
Answer: A
NETWORK - Consonants: N, T, W, R, K (reverse: K, R, W, T, N) + Vowels: E, O (forward: E, O) = KRWTNETO (arrangement: TRWNETO).
Q.17Medium
In a complex pattern, RAINBOW is coded as R-1-9-14-2-15-23. What is THUNDER coded as?
Answer: A
Letters converted to alphabet positions: T=20(shown as T), H=8, U=21, N=14, D=4, E=5, R=18.
Q.18Medium
MODERN is coded as MORNED using transposition. What rule is applied?
Answer: B
MODERN: M-O-D-E-R-N. Swap E and R (positions 4,5 become R,E): MORNED requires E-N swap at 5,6 positions: MOD-R-E-N = MODRNE (verify: swap gives MORNED when N and E swap).
Q.19Medium
TRAFFIC is coded with a rule: first letter becomes last, last becomes first, middle remains same. What code do we get?
Answer: A
TRAFFIC: T (1st) ↔ C (7th), R (2nd) ↔ A (6th), A (3rd) ↔ F (5th), F (4th) stays. Result: CARFFIT.
Q.20Medium
In a code, vowels are replaced by the next number (A=2, E=6, I=10, O=16, U=22) and consonants remain same. PHONE would be coded as?
Answer: A
P=P, H=H, O=16, N=N, E=6. So PHONE becomes PH16N6.
