CD: 916 :: ?: 100144

  1. A
    HG
  2. B
    MO
  3. C
    RS
  4. D
    JL

Solution & Step-by-step Explanation

Let's analyze the relationship between the letters and the numbers:
The positional values of the letters C and D in the English alphabet are:

C=3

D=4

Now, square these positional values:

3
2
=9

4
2
=16

Combining these squares gives 916.

Applying the same logic to the given number 100144:
We split the number into two parts which are perfect squares: 100 and 144.

100


=10

144


=12

The letters corresponding to positional values 10 and 12 are:

10→J

12→L

Therefore, the missing pair is JL.
