Question

In this question, a group of numbers/symbols is coded using letters as per the table given below and the conditions which follow. The correct combination of codes following the conditions is your answer.

Conditions:

• (i) If the first element is an even number and the last element is also an even number, the codes for these two (the first and the last elements) are to be interchanged.

• (ii) If the second element is an even number and the fifth element is a symbol, the codes for these two (the second and the fifth elements) are to be interchanged.

• (iii) If the fourth element is a symbol and the sixth element is also a symbol, both these elements (the fourth and the sixth elements) are to be coded as N.

Question:

4 6 $ 7 4 # @ 2

• A. HFEΜΗΤΡΖ
• B. ZFEΜΗΤΡΗ
• C. ZFEΝΗΝΡΗ
• D. ZHEMFTPH

Answer 1

Answer:

B. ZFEΜΗΤΡΗ

The correct code combination for the sequence 4 6 7 4 # @ 2 is Z F M E H T P H.

1. Find the Base Codes from the Table:
   Let's check the direct code for each element in the sequence 4 6 7 4 # @ 2:

   • 4 $\rightarrow$ H

   • 6 $\rightarrow$ F

   • $$ --->E

   • 7 \rightarrow$<b>M</b></p></li><li><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;">4$\rightarrow H

   • #\rightarrow$T</b></p></li></ul><ul style="color: rgb(0,0,0);"><li><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;">@$\rightarrow$<b>P</b></p></li><li><p data-pxy="true" style="color: rgb(0,0,0); margin-top: 2px; margin-bottom: 2px;">2$\rightarrow$ Z

   Base Code Sequence: H F E M H T P Z

2. Check the Conditions:

   • Condition (i): The first element (4) is an even number and the last element (2) is also an even number. This condition applies. Therefore, the codes for the first and last elements must be interchanged (H and Z swap places).

   • Condition (ii): The second element (6) is an even number, but the fifth element (4) is a number, not a symbol. This condition does not apply.

   • Condition (iii): The fourth element (7) is a number, not a symbol. This condition does not apply.

3. Apply the Change:

   • Swapping the first and last letters transforms H F E M H T P Z into Z F E M H T P H.
