Question

In a certain code language, 'D' is coded as '16', 'B' is coded as '4' and 'T' is coded as '400'. How will 'H' be coded in the same language?

1. A. 36
2. B. 64 (Correct answer)
3. C. 25
4. D. 8

Correct Answer

Option B — 64

Detailed Solution & Explanation

The correct answer is 64.

Key Points

• Each letter is coded as the square of its position in the alphabet: D=4→4²=16, B=2→2²=4, T=20→20²=400.
• H is the 8th letter, so 8² = 64.

Additional Information

• Letter-to-number codes almost always run through alphabet position, so write the position first and then look for the arithmetic.
• Squares of positions are a standard SSC device; so are position × a constant, and position + a constant.
• Verifying against a large value like T = 20 → 400 is the quickest way to rule out linear rules, since a linear rule could never reach 400.
