Alphanumeric Series MCQ - 1 - Question 28

Study the following arrangement and answer questions given:

A ^ D N 3 & G E 2 9 Q \$ * C S 1 ) R I 4 M @ ! Z H 5 © K L U

Q. Complete the series: N&D E9G \$CQ ?

Detailed Solution for Alphanumeric Series MCQ - 1 - Question 28

Explanation:
To solve this problem, we need to identify a pattern or sequence in the given arrangement. The arrangement is:
A ^ D N 3 & G E 2 9 Q \$ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Now, let's analyze the given series to be completed: N&D E9G \$CQ
We can observe the following pattern:
- The first element of each group is a letter that appears in the original arrangement with a gap of 5 letters between them. For example, N (A ^ D N...), E (G E 2 9 Q...), and \$ (* C S 1 ) R...).
- The second element is a symbol or number that appears exactly two steps after the first element in the original arrangement. For example, & (D N 3 &...), 9 (E 2 9 Q...), and C (\$ * C S...).
- The third element is a letter that appears exactly three steps after the second element in the original arrangement. For example, D (N 3 & G E...), G (E 2 9 Q \$...), and Q (\$ * C S 1 ) R...).
Using this pattern, we can find the next group in the series:
- The first element should be a letter with a gap of 5 letters after Q in the original arrangement: R (1 ) R I 4...).
- The second element should be a symbol or number two steps after R in the original arrangement: 1 (R I 4 M @ ! Z H 5 © K L U).
- The third element should be a letter three steps after 1 in the original arrangement: S (1 ) R I 4 M @ ! Z H 5 © K L U).
So, the next group is 1RS. Therefore, the answer is:

D: 1RS
