Question 1
If PREVENTION is coded as DWDSOOSJNO then how will CONTENTION will be coded ?
a) DUBPMOSJON b)DUMPBOSJNO c)OSJDUMPBON d)JDMUNOSBOP
Answer : b)DUMPBOSJNO
Reason :
This is actually a bit tough one and would require some application and analysis of options to arrive at the correct one.
The word PREVENTION is first split into two halves PREVE and NTION. In both halves each odd place letter is replaced with the previous letter and each even place letter is replaced with the next letter in alphabet.By doing so the halves would now become OSDWD and OSJNO respectively. Then the first half is reversed while the second half is preserved/kept as it is to arrive at our code DWDSOOSJNO .
By applying the above logic to CONTENTION you can get to the answer DUMPBOSJNO.
Question 2
Read the following sentences carefully and answer the below questions:
"Sky is blue" is coded as "tau hok sek"
"Cloud covers sky" is coded as "kef sek raq"
"Its raining" is coded as "hsf awe"
a) What is the code used for sky?
a)sek b)awe c)raq d)hok
Answer : a)sek
Reason :
These type of questions are easy to answer.
The word sky is occuring in first and second statements. No other word is common between first and second statements. This implies that the code that is common between first and second statements would be the answer. The code 'sek' is common between first and second statements and hence is the answer.
Question 3
In a code language SECURITY is coded as CUESTYRI then the code for WATCHMAN is ?
a)TCWAANHM b)TCWANAMH c)TCAWANHM d)TAWCHANM
Answer : c)TCAWANHM
Reason :
Let us check how SECURITY would had got its code CUESTYRI .
The word SECURITY is split into two halves SECU and RITY .
Now SECU is further split into SE and CU. Letters of first sub half SE is reversed. Then the halves are switched places to get CUES. ...(1)
Similarly the second half RITY is split into RI and TY. Now, the halves are just switched to get TYRI....(2)
Combining 1 and 2 we get CUESTYRI. This is how the code for SECURITY is arrived.
Applying similar logic to WATCHMAN we can get the answer TCAWANHM.
