If FRIEND is coded as HUMJTK, how is CANDLE written in that code ?

Correct Answer: QDFHS

Explanation:

The letter of the word are written in a reverse order and then each letter is moved one step backward to obtain the code.

Correct Answer: tod

Explanation:

Justification:   

In statements A and B, the common code word is 'na' and the common word is 'water'.

So, 'na' means 'water'.

In statements B and D, the common code word is 'jo' and the common word is 'life'.
So, 'jo' means 'life'.
Thus, in statements B, 'tod' represents 'is'.

Correct Answer: 46

Explanation:

In the given code, A = 2, B = 4, C = 6,.... , Z = 52.

So, ACT = 2 + 6 + 40 = 48 and

BAT = 4 + 2 + 40 = 46

Correct Answer: 8

Explanation:

Justification: 

In the first and second statements, the common code digit is '4' and the common word is 'good'.

So, '4' stands for 'good'.
In the second and third statements, the  common code digit is '7' and the common word is 'pictures'.
So, '7' means 'pictures'.
Thus, in the second statements, '8' means 'see'.

Correct Answer: EOJDJEFM

Explanation:

- There are 8 letters in the word.

- The coded word can be obtained by taking the immediately following letters of word, expect the first and the last letters of the given word but in the reverse order. That means, in the coded form the first and the last letters have been interchanged while the remaining letters are coded by taking their immediate next letters in the reverse order.

Correct Answer: 125

Explanation:

Z C o d e ? 26 ? 26 2 ? 13 ? 13 3 = 2197

$$\begin{gathered} R C o d e ? 18 ? 18 2 ? 9 ? 9 3 = 729 \\ \end{gathered}$$

Similarly,  J C o d e ? 10 ? 10 2 ? 5 ? 5 3 = 125

Correct Answer: 214673

Explanation:

 The alphabets are coded as shown :

 

$$\begin{gathered} R O S ? E C H A I P \\ 6 8 2 1 7 3 4 5 9 \end{gathered}$$

 

So, in SEARCH,

 

S ia coded as 2,
E as 1,
A as 4,
R as 6,
C as 7,
H as 3.
Thus, the code for SEARCH is 214673

Correct Answer: A only

Explanation:

Justification:      

We can find the code for 'home' from the second and third statements.

For finding the code for 'they', we need the code for 'go' which cannot be determined from the given data.
Clearly, statement A is not necessary.
