- 2. 1) In a certain code language, '134' means 'good and tasty'; '478' means 'see good pictures' and '729' means 'pictures are faint'. Which of the following digits stands for 'see'? A) 9 B) 2 C) 1 D) 8
- 3. Answer: D) 8 Explanation: Justification: In the first and second statements, the common code digit is '4' and the common word is 'good'. So, '4' stands for 'good'. In the second and third statements, the common code digit is '7' and the common word is 'pictures'. So, '7' means 'pictures'. Thus, in the second statements, '8' means 'see'
- 4. 2). If Z = 52 and ACT = 48, then BAT will be equal to A) 39 B) 41 C) 44 D) 46
- 5. Answer: D) 46 Explanation: In the given code, A = 2, B = 4, C = 6,.... , Z = 52. So, ACT = 2 + 6 + 40 = 48 and BAT = 4 + 2 + 40 = 46
- 6. 3). If ROSE is coded as 6821, CHAIR is coded as 73456 and PREACH is coded as 961473, what will be the code for SEARCH ? A) 246173 B) 214673 C) 214763 D) 216473
- 7. Answer: B) 214673 Explanation: The alphabets are coded as shown : R O S E C H A I P 6 8 2 1 7 3 4 5 9 So, in SEARCH, S is coded as 2, E as 1, A as 4, R as 6, C as 7, H as 3. Thus, the code for SEARCH is 214673
- 8. 4). In a certain code language, '3a, 2b, 7c' means 'Truth is Eternal'; '7c, 9a, 8b, 3a' means 'Enmity is not Eternal' and '9a, 4d, 2b, 8b' means 'Truth does not perish'. Which of the following means 'enmity' in that language ? A) 3a B) 7c C) 8b D) 9a
- 9. Answer: C) 8b Explanation: Justification: In the second and third statements, the common code is '9a' and the common word is 'not'. So, '9a' means 'not'. In the first and second statements, the common codes are '7c' and '3a' and the common words are 'is' and 'Eternal'. So, in the second statement, '8b' means 'enmity'.
- 10. 5).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) CHMFINTK B) LNKTCHMF C) LNTKCHMF D) NITKHCMF
- 11. Answer: C) LNTKCHMF Explanation: Each letter in the word is moved one step backward to obtain the corresponding letter of the code
