Sol. Ans.(d).

It is given that A to Z are numbered in same order as 1 to 26 (the word “respectively”).

Now, GHI must logically become 789. But we are given GHI = 1578.

Note that 789 x 2 = 1578.

Also given that DEF = 912. But 912 = 456 x 2 and 456 = DEF in the given coding scheme.

So logic is “doubling of give number code”.

So correct answer would be ABC = 123 = 246.
