# Coding and Decoding Questions & Answers : Logical Reasoning

1.

If white is called blue, blue is called red, red is called yellow, yellow is called green, green is called black, black is called violet and violet is called orange, what would be the colour of human blood ?

A.) Yellow
B.) Red
C.) Green
D.) Violet

The colour of the human blood is 'red' ans as given, 'red' is called 'yellow'.
So, the colour of human blood is 'yellow'.

2.

If in a certain language if ENTRY is coded as 12345 and STEADY is coded as 931785, then state which is the correct code for below word. SEDATE

A.) 918731
B.) 814195
C.) 954185
D.) 614781

The alphabets are Coded as shown :
E   N   T   R   Y   S   A   D
1   2   3   4   5   9   7   8
S is coded as 9,
E as 1,
D as 8,
A as 7    and
T as 3.
So, SEDATE is coded as 918731.

3.

If in a code language, COULD is written as BNTKC and MARGIN is written as LZQFHM, how will MOULDING be written in that code ?

A.) LNKTCHMF
B.) NITKHCMF
C.) LNTKCHMF
D.) CHMFINTKB

Each letter in the word is moved one step backward to obtain the corresponding letter of the code.

4.

In a certain code, MENTION is written as LNEITNO. How is PATTERN written in that code ?

A.) OTAETNR
B.) ATAETNR
C.) STAETNR
D.) OTAESNR

In the given word, we can analyse that,
M is decreased by 1, M-1 = L, and other words are interchanged,
EN - NE
TI - IT
ON - NO
So PATTERN will be
P -1 O
AT - TA
TE - ET
RN - NR

5.

If GIVE is coded as 5137 and BAT is coded as 924, how is GATE coded ?

A.) 5247
B.) 2547
C.) 4247
D.) 4547

The alphabets are coded as shown :
G   I   V   E   B   A   T
5   1   3   7   9   2   4
So, G is coded as 5,
A as 2,
T as 4   and
E as 7.
Thus, the code for GATE is 5247.
