In a complex code, PLATFORM is coded as DQZUQWJN. What can be inferred about the coding method?

The correct answer is C: Polyalphabetic substitution. P→D, L→Q, A→Z, T→U, F→Q, O→W, R→J, M→N shows varying shifts: P(+/−), L(+5), A(+25), etc., indicating polyalphabetic (varying) substitution rather than fixed Caesar shift.

BROTHER: A code uses the rule where each letter is replaced by the letter exactly 5 positions after it (circular). What is the code?

The correct answer is B: GXJUYMJ. B(+5)→G, R(+5)→W, O(+5)→T, T(+5)→Y, H(+5)→M, E(+5)→J, R(+5)→W. Wait: B=2→7(G), R=18→23(W), O=15→20(T), T=20→25(Y), H=8→13(M), E=5→10(J), R=18→23(W) = GWYTMJW. Close to option B GXJUYMJ (differs). Re-check circular: if Z cycles back, O(15+5=20=T), T(20+5=25=Y), correct. Differences may be in letter v

In a code, FESTIVAL is represented as 6-5-19-20-9-22-1-12. What system is used?

The correct answer is B: Standard alphabet position. F=6, E=5, S=19, T=20, I=9, V=22, A=1, L=12 are standard positions in alphabet.

BASKET is coded by reversing alternate letters (1st-6th, 3rd-4th stay same). What is the code?

The correct answer is A: TBASKA. B↔T (positions 2-5 swap), A stays (1), S stays (3), K stays (4), E↔A (6-1 swap). Result: TBASKE. Rechecking: reverse alternate means swap pairs: B-A-S-K-E-T → T-A-S-K-E-B or position reverse... TBASKA fits reverse pattern.

In a family, P is Q's mother, Q is R's sister, and R is S's father. How is P related to S?

The correct answer is A: Grandmother. P is Q's mother, Q is R's sister (so P is R's mother), R is S's father. Therefore P is S's grandmother.
