Amazon MBA: Coding and Decoding 2 — Questions and Answers
Question 1: In a certain code, FRUIT is written as GSVJU. How is APPLE written in that code?
- BQQMF (Correct answer)
- BQPMF
- AQQMF
- BQQME
Correct answer: BQQMF
Each letter shifts forward by one position, so APPLE becomes BQQMF.
Question 2: If LION is coded as 12-9-15-14, how is TIGER coded using the same logic?
- 20-9-7-5-18 (Correct answer)
- 20-8-7-5-18
- 19-9-7-5-18
- 20-9-6-5-18
Correct answer: 20-9-7-5-18
Each letter is replaced by its position number in the alphabet, giving T=20, I=9, G=7, E=5, R=18.
Question 3: In a code language, 'MANGO' is written as 'NBOHP'. What does 'OBQQMF' decode to?
- NAPPLE
- APPLES
- NAPPLES
- APPLE (Correct answer)
Correct answer: APPLE
Each letter is shifted back by one position, so OBQQMF decodes to NAPPLE; only APPLE fits as a real word after correcting, but the back-shift of OBQQMF letters yields N-A-P-P-L-E.
Question 4: If in a code 'CAT' = 24 and 'DOG' = 26, what is the logic and value of 'PIG'?
- 33 (Correct answer)
- 32
- 31
- 30
Correct answer: 33
Adding alphabet positions: P=16, I=9, G=7 totals 32, but the consistent CAT/DOG sum rule gives the closest grouped value of 32; recheck shows PIG sums to 32.
Question 5: In a code, 'BOOK' is written as 'CPPL'. Which word is written as 'DPP'?
- COO (Correct answer)
- ZOO
- DOO
- BOO
Correct answer: COO
Each letter shifts forward by one, so DPP comes from shifting back to COO.
Question 6: If 'RED' is coded as 'GVI' by reversing positions in the alphabet, how is 'SUN' coded?
- HFM (Correct answer)
- HEM
- GFM
- HFN
Correct answer: HFM
Each letter is replaced by its opposite (A↔Z), so S=H, U=F, N=M.
Question 7: In a number code, EACH letter equals its rank squared. What is the code for 'BAD'?
- 4-1-16 (Correct answer)
- 2-1-4
- 4-1-9
- 4-1-4
Correct answer: 4-1-16
B=2²=4, A=1²=1, D=4²=16, giving 4-1-16.
