Tricks to Solve Alphanumeric Series Easily: Part 2

In this article we learn how to solve Alpha-numerical series easily by developing tricks

Study the following digit-letter-symbol sequence carefully and answer the questions given below:

2 R * C f 8 E $ G 2 # 4 9 L c % B < K 1 & A W ? P e + Q @ 7 F 6

Question 1:

If the first half of the series is written in reverse order, then which Element will be twenty-first from the right end?

TRICK: 

No need of writing the series in reverse order
Step 1: Count the total number of alpha-numericals =32
Step 2: As we are considering half of the series, divide by two =32/2=16
Required 21R = 16R+5R
Instead of taking 5R take 5L (since first half is reversed)
16R+5L=f (Answer)

Question 2:

Which element will be twenty-first from the right end, if second half of the series is reversed?

TRICK: 

No need of writing the series in reverse order
Step 1: Count the total number of alpha-numericals =32
Step 2: As we are considering half of the series, divide by two =32/2=16
Required 21R = 16R+5R
16R+5R (belongs to first half do not reverse) =4 (Answer)

Question 3:

If the above sequence is written in reverse order, then which element will be 5th to the right of 16th element from the right end?

TRICK: 

If both are in same direction (subtract)
=To From
=5R - 16R
=11R
=11L (trick: To reverse order change R to L)
=# (Answer)

Question 4:

Which element is seventh to the left of sixteenth element from the right in the above sequence?

TRICK: 

If both are in opposite direction (add)
=To From
=7L + 16R
=23R=W (Answer)
