Test: Coding & Decoding - 3 - Question 1

Direction: Study the following question carefully and choose the right answer.

If REASON is coded as 5 and BELIEVED as 7, then what is the code for GOVERNMENT?

Detailed Solution: Question 1

Clearly, each word is coded by the numeral which is 1 less than the number of letters in the word.
Since, there are 10 letters in the word GOVERNMENT, so required = 10 – 1 = 9.
Hence, option C is correct.

Test: Coding & Decoding - 3 - Question 2

Direction: Study the following question carefully and choose the right answer.

If ACNE can be coded as 3, 7, 29, 11 then BOIL will be coded as ….?

Detailed Solution: Question 2

In the given coding system, we have:

So, the code for BOIL is 5, 31, 19, 25.
Hence, option D is correct.

Test: Coding & Decoding - 3 - Question 3

Direction: Study the following question carefully and choose the right answer.

If RED is coded as 6720, then how would GREEN be coded?

Detailed Solution: Question 3

Clearly, the order of letters in the word is reversed and then each letters is replaced by the numeral denoting its position in the English alphabet. Next, 2 is added to each numeral and the numerals so obtained are joined together physically to get the code. Thus, we have :

RED → DER → 4/5/18 → 6/7/20 → 6720.

GREEN → NEERG → 14/5/5/18/7 → 16/7/7/20/9 → 1677209.
Hence, option B is correct.

Test: Coding & Decoding - 3 - Question 4

Direction: Study the following question carefully and choose the right answer.

IF E = 5, PEN = 35, then PAGE = ?

Detailed Solution: Question 4

Clearly, putting A = 1, B = 2, C = 3, D = 4, E = 5, ..........M = 13, ...... x = 24, Y = 25, Z = 26, we have :
PEN = P + E + N = 16 + 5 + 14 = 35.
So, PAGE = P + A + G + E = 16 + 1 + 7 + 5 = 29.
Hence, option C is correct.

Test: Coding & Decoding - 3 - Question 5

Direction: Study the following question carefully and choose the right answer.

If RAM is coded as 5, GUI is coded as 1, then what is the code for SAP?

Detailed Solution: Question 5

The numeric value of the letters (considering A to be 1 and Z to be 26) is added and simplified to obtain a single digit.

For RAM, the numeric value of R, A and M is 18, 1 and 13 respectively. Their sum is 32, Now 32 is further simplified to obtain a single digit by adding 3 and 2, which gives us 5 as the final value.
Similarly for GUI, the numeric value of G,U and I is 7, 21 and 9 respectively. Their sum is 37, which is simplified as 3 + 7 = 10 => 1 + 0 = 1.
Similar process will be done to obtain the code for SAP, the numeric value of S, A and P is 19, 1 and 16 respectively. Their sum is 36, which is simplified as 3 + 6 = 9.
So, the code for SAP is 9.
Hence option (B) is correct.

Test: Coding & Decoding - 3 - Question 6

Direction: Study the following question carefully and choose the right answer.

If PLANT is coded as TNBLP, then LOGIC will be coded as

Detailed Solution: Question 6


Hence, option A is correct.

Test: Coding & Decoding - 3 - Question 7

Direction: Study the following question carefully and choose the right answer.

If in a code language, PAINT is written as 74128 and EXCEL is written as 93596, then how will ACCEPT be written in that language?

Detailed Solution: Question 7

Test: Coding & Decoding - 3 - Question 8

Direction: Study the following question carefully and choose the right answer.

If STAFF is coded as $2#55 and FOLD is coded as 5@3% then how is STOLL written in that code language?

Detailed Solution: Question 8



∴ STOLL → $2@33
Hence, option B is correct.

Test: Coding & Decoding - 3 - Question 9

Direction: Study the following question carefully and choose the right answer.

If ZOO is coded as 2, TAN is coded as 8, then what is the code for WAR?

Detailed Solution: Question 9

Convert each letter in the word into its alphabetical position (A=1, B=2, ..., Z=26).

For the word "ZOO":
Z = 26, O = 15, O = 15
Total = 26 + 15 + 15 = 56
Add digits of 56 → 5 + 6 = 11 → 1 + 1 = 2
Hence, ZOO is coded as 2.

For the word "TAN":
T = 20, A = 1, N = 14
Total = 20 + 1 + 14 = 35
Add digits of 35 → 3 + 5 = 8
Hence, TAN is coded as 8.

For the word "WAR":
W = 23, A = 1, R = 18
Total = 23 + 1 + 18 = 42
Add digits of 42 → 4 + 2 = 6
Hence, WAR is coded as 6.

Final Answer: b) 6

Test: Coding & Decoding - 3 - Question 10

Direction: Study the following question carefully and choose the right answer.

In a certain code, RAIN is written as 8$%6 and MORE is written as 7#8@. How is REMAIN written in that code?

Detailed Solution: Question 10


Thus, the code for REMAIN is 8@7$%6.
Hence, option D is correct.
