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: 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
