The given series is: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 ZAccording to the Questions,The second half of the following alphabet is written in the reverse orderThe new series will be:A B C D E F G H I J K L M Z Y X W V U T S R Q P O NWe know, If opposite directions are given then we add the numbers and If the same directions are given then we subtract the numbers.Here, opposite directions are given in the question, therefore, we will add the numbers.? 10 + 9 = 19Therefore, the 19th letter from right in the new series will be the answer.A B C D E F G H I J K L M Z Y X W V U T S R Q P O NHence, the correct answer is 'H'.Alternate Method The given series is: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 ZThe new series will be:A B C D E F G H I J K L M Z Y X W V U T S R Q P O NNow, The ninth letter from the right is 'V'.The tenth letter to the left of 'V' is 'H'.A B C D E F G H I J K L M Z Y X W V U T S R Q P O NHence, the correct answer is 'H'.Additional Information1) If opposite directions are given then add the numbers.2) If the same directions are given then subtract the numbers.
