If RESULT is coded as 15 and BELOW as 12, then what is the code for GOAT?

  1. 10

  2. 9

  3. 8

  4. 6

  5. None of these


Correct Option: B
Explanation:

Number of letters in word RESULT = 6; Code of word RESULT = (6 - 1)*3 = 15. Similarly, number of letters in the word BELOW = 5, then the code of the letter BELOW = (5 - 1)*3 = 12. So, GOAT = (4 - 1)*3 = 9.

In a certain code, DAD is written as WZW and SON is written as HLM, then WIFE will be written as

  1. DRUV

  2. DSUV

  3. DQVU

  4. DRVW

  5. None of these


Correct Option: A
Explanation:

The word DAD = WZW, which means the starting position in English alphabet of D = 4. So, the 4th position in English alphabet from end = W, and so on. That means that from the starting position and from the end: D 4 WA 1 ZD 4 W. Similarly, S 8 HO 15 LN 14 M, so WIFE = DRUV.

In a certain code, PAGES is written as RDIHU and WRITE is written as YUKWG. How will OFFER be written in the same code?

  1. RVKGU

  2. QHHGT

  3. RWJHU

  4. PWIHS

  5. None of these


Correct Option: B
Explanation:

According to the English alphabet, P (+2) R, A (+2) D, G (+2) I, E (+2) H, S (+2) U. Similarly, W (+2) Y, R (+2) U, I (+2) K, T (+2) W, E (+2) G. So, OFFER = QHHGT.

If SPEAK is written as 18154010 in a certain code, how would MOUNTAIN be written in that code?

  1. 12142013190138

  2. 14122013190813

  3. 12142013190813

  4. 12142013019813

  5. None of these


Correct Option: C
Explanation:

SPEAK = 18154010, so according to the English alphabetical position, this code is moving on the pattern of S = (alphabetical position of S) - 1 = 19 - 1 = 18; P = (alphabetical position of P) - 1 = 16 - 1 = 15; E = (alphabetical position of E) - 1 = 5 - 1 = 4, and so on. Therefore, MOUNTAIN = 12142013190813.

If 8514 stands for HEAD, then 31385 stands for

  1. CATCH

  2. CLASS

  3. CACHE

  4. COMES

  5. None of these


Correct Option: C
Explanation:

It is observed that 8 is the alphabetical position of H; 5 is the alphabetical position of E; 1 is the alphabetical position of A; and 4 is the alphabetical position of D. Therefore, 31385 = CACHE.

If in a certain language, MADNESS is coded as 21, then how is WISER coded in that language?

  1. 15

  2. 25

  3. 20

  4. 30

  5. None of these


Correct Option: A
Explanation:

Number of letters in MADNESS = 7, then three times the number of letters = 7 * 3 = 21. Therefore, WISER = 5 * 3 = 15.

If FUSE is written as BQOA in a certain code, how would BULB be written in that code?

  1. QXHX

  2. XQHX

  3. FYOF

  4. FOYF

  5. None of these


Correct Option: B
Explanation:

It is observed that according to the alphabetical position, F (-4) B, U (-4) Q, S (-4) O, E (-4) A.  So, BULB = XQHX.

In a certain code, BAND is written as CCQH. How is SWIM written in that code?

  1. VXDQ

  2. TYLQ

  3. RUFI

  4. TXJN

  5. None of these


Correct Option: B
Explanation:

It is observed that the code of the word BAND is moving on +1, +2, +3, +4 according to alphabetical position. This means BAND = CCQH. Similarly, SWIM = TYLQ.

In a certain code, TWICE is written as BZFTQ, then how would TRIPLE be written in the same code?

  1. QIMFOB

  2. WULSOH

  3. QOFMIB

  4. BIMFOQ

  5. None of these


Correct Option: D
Explanation:

According to the alphabetical position, first of all, reverse the letters of TWICE from right to left and move -3 positions back. This means TWICE = ECIWT => BZFTQ So, TRIPLE = ELPIRT => BIMFOQ This is the correct answer.

If FRAUD is coded as GUFBM, how is KEPT written in that code?

  1. LHUA

  2. LFQU

  3. AHUL

  4. LHAU

  5. None of these


Correct Option: A
Explanation:

According to alphabetical position, the code of word FRAUD is moving on the pattern +1, +3, +5, and so on. So, KEPT = LHUA.

If PERSONAL is written as 45896723 in a certain code, how will SALE be written in that code?

  1. 9235

  2. 9325

  3. 9523

  4. 8235

  5. None of these


Correct Option: A
Explanation:

When it is observed that PERSONAL = 45896723, then P = 4, E = 5, R = 8, S = 9, O = 6, N = 7, A = 2, L = 3. So, SALE = 9235.

In a certain code, if ROMANCE is written as PNKZLBC, how will MOUSE be written in that code?

  1. KSNRC

  2. KNSCR

  3. NKSRC

  4. KNSRC

  5. None of these


Correct Option: D
Explanation:

 ROMANCE = PNKZLBC It is found that according to the English alphabetical position, this code is moving on the pattern of -2, -1, -2, -1 and so on. Therefore, MOUSE = KNSRC

If in a code language, PARTNER is written as 7412851 and RACE as 1435, then how will ACCEPT be written in that language?

  1. 433572

  2. 533572

  3. 455572

  4. 233574

  5. None of these


Correct Option: A
Explanation:

PARTNER = 7412851 and RACE = 1435 Therefore, A = 1, C = 3, E = 5, P = 7 and T = 2 So, ACCEPT = 433572

If DATE is coded as 5183 and GOES is coded as 9734, then TASTE is coded as

  1. 81438

  2. 81483

  3. 84738

  4. 83872

  5. None of these


Correct Option: B
Explanation:

DATE = 5183 and GOES = 9734; D = 5, A = 1, T = 8, E = 3, O = 7 and S = 4. So, TASTE = 81483.

If in a certain code, MILESTONE is written as LJKFRUNOD, how is POLLUTION written in that code?

  1. QPMMVUJPM

  2. ONKKTSHNM

  3. OPKMTUHPM

  4. MPKMTUHPO

  5. None of these


Correct Option: C
Explanation:

It is observed that according to the English alphabet, the given code is moving on the pattern -1, +1, -1, +1 and so on. Therefore, required code of POLLUTION = OPKMTUHPM.
