Study the given letter-symbol series and answer the question that follows.
L @ S * J * B U # W R < E @ N $ # B * H ! A & L < W Q
How many symbols are immediately followed by a consonant and immediately preceded by a vowel?

A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow. Study the given codes and conditions and answer the question that follows.

Note: If none of the conditions apply, then codes for the respective number/symbol are to be followed directly as given in the table.

Conditions:
If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged.
If the first element is an odd number and the last an even number, the first and last elements are to be coded as ©.
If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
What will be the code for the following group?

5 3 + 4

A group of numbers and symbols is coded using letter codes as per the codes given below and the conditions that follow. Study the given codes and conditions and answer the question that follows.
Note: If none of the conditions apply, then codes for the respective number/symbol are to be followed directly as given in the table.

Conditions:
I. If the first element is a symbol and the last a number, the codes for these two (the first and the last elements) are to be interchanged.
II. If the first element is an odd number and the last an even number, the first and last elements are to be coded as ©.
II. If both second and third elements are perfect squares, the third element is to be coded as the code for the second element.
What will be the code for the following group?
@ 3 5 7

​Conditions:
1. If the 1st letter is a vowel and the last letter is a consonant, their codes are to be interchanged.
2. If the 2nd letter is a vowel and the last letter is a consonant, both are to be coded as ‘W’.
3. If the 3rd and 4th letters are consonants, both are to be coded as the code for the 3rd letter.
4. If the 1st and 2nd letters are vowels, then both are to be coded as ‘Q’.
What will be the code for the following group?
APUXR​

A group of numbers/symbols is coded using letter codes as per the codes given below and the conditions that follow. If none of the conditions apply, then codes for the respective number/symbol to be followed directly as given in the table.

Conditions:
(i) If the first element and the last element is a number, the codes for these two (the first
and the last elements) are to be interchanged.
(ii) If the first element is an odd number and the last an even number, the first and last
elements are to be coded as ©.
(iii) If both the second and third elements are perfect squares, the third element is to be
coded as the code for the second element.
What will be the code for the following group?
7 2 ∆ 8 9 @ 3

Letters and their number codes are given in the following table:

You have to find out which of the alternatives has the correct coded form of 'EMRS'.​
