Q3. Which of the following follows the same logic as the series C-32, D-64, E-128, F-256? (A) X-2, Y-4, Z-8 (B) A-1, B-3, C-9 (C) P-10, Q-20, R-30 (D) M-100, N-200, O-300 Answer Key and Explanations Correct Answer: (B) G-512 Explanation
🔹 C (3rd letter) x $2^5$ = 32 🔹 D (4th letter) x $2^4$ = 64... wait no. 🔹 It's actually just straight doubling!
| Value | Bits per channel | Total colors (RGB) | |-------|------------------|--------------------| | 32 | 5 bits | 32,768 (5-5-5 RGB) | | 64 | 6 bits | 262,144 (6-6-6 RGB, rare) | | 128 | 7 bits | 2,097,152 (7-7-7 RGB, nonstandard) | | 256 | 8 bits | 16,777,216 (Truecolor) |
