Actually guys, this qn is WRONG like you know, 195 rounded off to tens is of course 200. 20 rounded of is 20 itself. 205 rounded off is 210. 305 rounded off is 310. So, the qn is WRONG!! Can you just believe that?

Reverse the following sequence of the English alphabets and then answer the following question.
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Which alphabet is 3rd to the right of 15th alphabet from the left end in the new series?

AL
BC
CO
DI


Question is given as "15th alphabet from left end", and, when it showed my answer wrong, and I checked the solution, it says "15th alphabet from right". When I tried to submit my query in the ''report an error'' section, it says that it is not a valid error. The correct answer should be option C.
