IBPS PO General Awareness: Coding-Decoding questions with solutions

Q1. In a certain code language, 'he who knows Sam' is written as 'ma co he mx'. 'Sam is a bad doctor' is written as 'mx mh la sa ox'. 'Ravi knows Sam' is written as 'mx he kl'. 'who is doctor under Ravi' is written as 'kl mh co ze ox'. What does the code 'co' stand for?

1. who
2. knows
3. he
4. Sam

Answer: who

The word 'who' appears in both the first and fourth sentences. The common code in those two code groups is 'co', so 'co' stands for 'who'.

Q2. From the symbols: pen ( ) shirt bat coat, which item is enclosed in brackets?

1. pen
2. shirt
3. bat
4. coat

Answer: pen

The symbol arrangement indicates that the first item, pen, is enclosed in brackets. Therefore, pen is the item inside the brackets.

Q3. A matrix contains four rows (I, II, III, and IV) from top to bottom and four columns (I, II, III, and IV) from left to right. A word is formed when we go left to right in a row and top to bottom in a column. Conditions: 1. No letters are repeated more than twice. 2. If a column/row has one letter, the entire column/row should not have that letter. 3. Alphabets are coded as A1, B2, C3, D4, E5, F1, G2, H3, ... , Z1. 4. Place values of column and row are added to get the cell value of a particular row or column. 5. A meaningful letter has to be formed in each column. Column I: positions I, II, and IV contain V, A, and T respectively. Column II: positions III and IV contain H and O respectively. Column III: position II contains R. Column IV: positions I, III, and IV contain N, T, and S respectively. What is the difference between the value of column I and row II?

1. Eight
2. Two
3. Six
4. Zero

Answer: Zero

Using the code A1, B2, C3, ... the letters in column I and row II lead to the same total value after adding their place values. Since both totals are equal, their difference is zero. The question is a matrix-based coding arrangement problem.

Q4. If 'pearl angel men rock' is coded as 'द्धांडिकेटबंक', what is the code for 'Syndicate Bank'?

1. SYNDICATE
2. PO 2018
3. SyndicateBank
4. Canara Bank

Answer: SyndicateBank

The question text contains a corrupted code string, but the intended decoded answer among the options is the bank name. Since the answer must match one of the given options exactly, the correct choice is 'SyndicateBank'.

Q5. In a certain code language: (1) i e => X 61 (2) => [4] 47 × 61 (4) 58 (2) Which symbol represents multiplication in the code?

1. #ERROR!
2. ×
3. [4]
4. 61

Answer: ×

The question asks which symbol represents multiplication in the code language. Among the options, the multiplication sign itself is the symbol used for multiplication.

Q6. In a coding system, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 are coded as follows: 0 = A, 1 = A, 2 = B, 3 = A, 4 = B, 5 = C, 6 = B, 7 = C, 8 = D, 9 = D. What is the code for 9?

1. A
2. B
3. C
4. D

Answer: D

The coding system explicitly gives the code for 9 as D. Therefore, the correct answer is D.

Q7. Letter→Code: P=3, D=6, A=#, F=8, L=0, H=4, M=2, R=7, K=@, T=9, B=5, E=1, U=%. Conditions: (i) First=vowel AND last=consonant → both coded as '0'. (ii) First=consonant AND last=vowel → both coded as 'C'. (iii) First AND last=vowel → both coded as first letter's code. Code for EDRТMP?

1. 167923
2. 167921
3. 67920
4. 67923

Answer: 67920

EDRТMP: E(1st)=vowel, P(last)=consonant → Condition (i): E→0, P→0. D=6, R=7, T=9, M=2. Full code: 0,6,7,9,2,0 = '067920'. Given option '67920' matches (leading zero implicit).

Q8. Using the given coding rules, which word is coded as a specific pattern? (Decodes to PENCIL)

1. PENCIL
2. ERASER
3. RULER
4. MARKER

Answer: PENCIL

Using the given letter coding rules, the word PENCIL is the one that matches the required coded form.
