Q:

# In a certain code PARINATH is written as QFQHOBSG and POLE as QPKD, how will SYNDROME  be written in that code?

 A) RXOEQNNF B) TZOEQNLD C) TZMCSPKD D) TZMCSPLD

Explanation:

Word is divided into groups of two letters each and then letters of each group move one place forward and one place backward alternatively as in English alphabet. Hence,

PERINATH => PE RI NA TH =>QFQHOBSG  and POLE => PO LE => QPKD

similarly,

SYNDROME => SY ND RO ME => TZMCSPLD

Q:

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

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

Explanation:

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

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

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