# Coding and Decoding questions:

##### 31) In a code sign DRLAL is coded as 62014314. How CAMEL is coded ?

a. 5315714

b. 35729310

c. 5313613

d. None of these

Explanation: Add two in the serial number of letters as :
D = 4th + 2 = 6
R= 18th + 2 = 20
L = 12th + 2 = 14
A = Ist + 2 = 3
L = 12th + 2 = 14.

##### 32) In a code language 35796 is written as 44887. Find the code for 46823.

a. 55914

b. 57194

c. 55934

d. 55745

Explanation: 3+1=4 of the code
5-1=4 of the code
7+1=8 of the code
9-1=8 of the code
6+1=7 of the code
as 3 5 7 9 6
+1 -1 +1 -1 +1
-----------------------------
4 4 8 8 7
So 4 6 8 2 3
+1 -1 +1 -1 +1
----------------------------------
5 5 9 1 4

a. DEEP

b. DOOR

c. DEER

d. FEED

Explanation: 12 10 10 8
F E E D

##### 37)In a certain code language 1 .Chip, Din, Chunk means students attend class 2. Din Sunk Dink means Arjun is student 3. Jump Mink Sink means Schools are good 4. Dink Mup Chimp means Teacher is teaching The code which is used for Arjun is ?

a. Sunk

b. Din

c. Dink

d. Chunk

Explanation: On the basis of Ist and IInd equations "students" = DIN
On the basis of IInd and IVth equations "is" = DINK
So Putting these two values into equation IInd we get the code for Arjun as SUNK.

##### 38)In a miitary code CAUTION is coded as UACITNO. How will you write MISUNDERSTAND?

a. SIMUNEDSRTAND

b. SIMNUEDSRATDN

c. SMIUNDERSTAND

d. None of the above
