Q:

# If ROSE is coded as 6821, CHAIR is coded as 73456 and PREACH is coded as 961473, what will be the code for SEARCH ?

 A) 246173 B) 214673 C) 214763 D) 216473

Explanation:

The alphabets are coded as shown :

${\color{Blue}&space;\begin{matrix}&space;R&space;&&space;O&space;&&space;S&space;&&space;E&space;&&space;C&&space;H&space;&&space;A&space;&&space;I&space;&&space;P\\&space;6&&space;8&&space;2&&space;1&&space;7&space;&&space;3&space;&&space;4&space;&&space;5&space;&&space;9&space;\end{matrix}}$

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

Q:

In certain code, TOGETHER is written as TCJRGEQR. In the same code JOINING will be written as?

 A) EPGPGQH B) QHPGPGE C) HQGPGPE D) EGPGPHQ

Explanation:

The letters at odd positions are each moved two steps backward and those at even positions are each moved two steps forward and the obtained code is reversed to get the corresponding letters of the code.

Q:

If Z= 2197 and R= 729. How would J be written in that code?

 A) 216 B) 124 C) 512 D) 125

Explanation:

$\inline Z \; code \Rightarrow 26 \Rightarrow \frac{26}{2}\Rightarrow (13)^{3}\Rightarrow 2197$

$\inline R\; code \Rightarrow 18 \Rightarrow \frac{18}{2}\Rightarrow (9)^{3}\Rightarrow 729$

$\inline Similarly\; \; J\; \; code\; \; \Rightarrow 10\Rightarrow \frac{10}{2}\Rightarrow (5)^{3}\Rightarrow 125$

Q:

In a certain code language , 'PROBLEM' is written as MPERLOB. How will 'PROBLEM' is written as MPERLOB. How will 'NUMBERS' be written in that code?

 A) SNUREMB B) SNRUBME C) SNRUEMB D) SNRUMEB

$\inline \begin{matrix} 1\; 2\; 3\; 4\; 5\; 6\; 7 & &7\; 1\; 6\; 2\; 5\; 3\; 4\\ PROBLEM & \Rightarrow & MPERLOB \end{matrix}$
$\inline \begin{matrix} 1\; 2\; 3\; 4\; 5\; 6\; 7 & &7\; 1\; 6\; 2\; 5\; 3\; 4\\ NUMBERS & \Rightarrow & SNRUEMB \end{matrix}$
