We analyze the transformation pattern: Each letter in the original word is shifted by a specific rule to obtain the corresponding coded letter. In this case, the shift appears to follow a consistent letter shift pattern, where each letter in the original word is moved a certain number of positions forward in the alphabet. For example:
Following the same pattern for the word BEACH:
Thus, BEACH is transformed into IDBFC based on the same letter-shifting pattern.
Therefore, the correct answer is (B) IDBFC.
Eight students (P, Q, R, S, T, U, V, and W) are playing musical chairs. The figure indicates their order of position at the start of the game. They play the game by moving forward in a circle in the clockwise direction.
After the 1st round, the 4th student behind P leaves the game.
After the 2nd round, the 5th student behind Q leaves the game.
After the 3rd round, the 3rd student behind V leaves the game.
After the 4th round, the 4th student behind U leaves the game.
Who all are left in the game after the 4th round?

The 12 musical notes are given as \( C, C^\#, D, D^\#, E, F, F^\#, G, G^\#, A, A^\#, B \). Frequency of each note is \( \sqrt[12]{2} \) times the frequency of the previous note. If the frequency of the note C is 130.8 Hz, then the ratio of frequencies of notes F# and C is:
