HI HERES UR ANSWER

Step-by-step explanation:

SORRY WHEN I SOLVED THIS QUESTION ,I GOT THE WRONG ANSWER,I DID ANOTHER SUM WHICH IS ALMOST SIMILAR TO UR QUESTION,JUST UNDERSTAND AND THEN WRITE

Given, XY = 600 and ABC = 6. Here, the coded pattern is as:

The position of letter A, B, C, X and Y in alphabetical order are 1, 2 , 3, 24  and 25 respectively.

So, XY = 24 X 25 = 600 and ABC = 1 X 2 X 3 = 6.

In the same manner the position of letter D, G and O is 4, 7 and 15.

So, GO + DO = 7 X 15 + 4 X 15 = 105 + 60 = 165

Hence, option (C) is the correct answer.
