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.
Number/symbol 6 % 8 5 $ & 3 @ # 7 + 4 9 6 Code S E A J L F W Q D P R B U T
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?
@ 4 8 5
To solve the coding problem, let's apply the provided conditions step-by-step:
-
Analyze the input group: @ 4 8 5.
- First element: @
- Second element: 4
- Third element: 8
- Last element: 5
-
Apply the relevant conditions:
- Condition 1: "If the first element is a symbol and the last a number." @ (symbol) and 5 (number) satisfy this condition. Thus, we should interchange the codes for the first and last elements.
- Condition 2: "If the first element is an odd number and the last an even number." This does not apply as @ is a symbol.
- Condition 3: "If both the second and third elements are perfect squares." Here, 4 is a perfect square (2²), but 8 is not. Therefore, this condition does not apply.
-
Determine the code for each element using the table:
- @ is coded as Q.
- 4 is coded as B.
- 8 is coded as A.
- 5 is coded as J.
-
Since Condition 1 applies, interchange the codes for the first and last elements:
- The code for @ becomes J, and the code for 5 becomes Q.
- Thus, the sequence after interchange: JBAQ
Therefore, the correct code for the group @ 4 8 5 is JBAQ.
Important Questions from Conditional Matrix
Select the option in which the numbers are related in the same way as are the numbers of the following sets.
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /deleting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)

iii. If a number begins and also ends with nonzero even digits, those two digits at the extreme ends should be coded as K.
iv. If a number begins and also ends with nonzero odd digits, those two digits at the extreme ends should be coded as J.
v. If the middle digit of a number is in multiples of 2, that digit should be coded as N.
vi. if the sum of the digits of a number is divisible by 6, then the second and eighth digits should be coded as Q.
