Free Amazon MBA: Coding and Decoding Questions and Answers

Question 1

How is LIGHT coded in a language if PROSE is coded as PPOQE in that language?

Accepted Answer

LGGFT

Answer

By analyzing the given code 'PROSE' to 'PPOQE', we observe a pattern: letters at odd positions (1st, 3rd, 5th) remain unchanged, while letters at even positions (2nd, 4th) are shifted two places backward in the alphabet. Applying this rule to 'LIGHT', the 1st, 3rd, and 5th letters (L, G, T) stay the same, and the 2nd and 4th letters (I, H) become G and F respectively, resulting in the code 'LGGFT'.

Question 2

How is BOMBAY coded in a language if MADRAS is coded as NBESBT in that language?

Accepted Answer

CPNCBZ

Answer

Analyzing the given code 'MADRAS' to 'NBESBT' reveals a simple pattern: each letter in the original word is shifted one position forward in the English alphabet. Applying this same rule to 'BOMBAY', each letter is incremented by one, transforming it into 'CPNCBZ'.

Question 3

Find the code for CARE if TOUR is written as 1234, CLEAR is written as 56784, and SPARE is written as 90847.

Accepted Answer

5847

Answer

This is a direct substitution coding problem. By comparing the given coded words, we can deduce the code for each letter. From 'CLEAR' (C=5, L=6, E=7, A=8, R=4) and 'SPARE' (S=9, P=0, A=8, R=4, E=7), we find consistent codes for A, R, E. Specifically, C=5, A=8, R=4, and E=7. Applying these substitutions to the word 'CARE' yields the code 5847.

Question 4

INSTITUTION is occasionally spelled as NOITUTITSNI. What format does PERFECTION take in that code?

Accepted Answer

NOITCEFREP

Answer

The coding pattern for 'INSTITUTION' to 'NOITUTITSNI' is a simple reversal of the original word. Applying this same reversal logic to 'PERFECTION' means writing the letters in reverse order. Therefore, 'PERFECTION' becomes 'NOITCEFREP' in that code.

Question 5

Where do you worship if Sand is encoded as Brick, Brick as House, House as Temple, and Temple as Palace?

Accepted Answer

Palace

Answer

The question asks where one would worship, and traditionally, people worship in a temple. According to the given coding scheme, 'Temple' is encoded as 'Palace'. Therefore, following the coded language, one would worship in a Palace.
