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?

The correct option is 64.

To find the code for the letter 'H', let's analyze the pattern by determining the standard alphabetical positions of the given letters (where A = 1, B = 2, C = 3, ..., Z = 26):

1. 'D' is coded as '16':
The alphabetical position of D is 4.

$4^2=16$

2. 'B' is coded as '4':
The alphabetical position of B is 2.

$2^2=4$

3. 'T' is coded as '400':
The alphabetical position of T is 20.

${20}^2=400$

We can see that the logic used here is squaring the numerical position of each letter in the English alphabet.

Applying this logic to find the code for 'H':
The alphabetical position of H is 8.

$8^2=64$

Therefore, 'H' will be coded as 64 in the same language.
