Q1. In a certain code language 'ALERT' is written as '11251820' and ' HERD' is written as '85184'. What will be the code for 'CLOTH' in that language?

a. 38152014

b. 31215218

c. 31215208

Sol- ALERT= 11251820 

Logic behind writing code  is just writing forward place value of each letter's.

A=1   L= 12  E =5  R= 18  T= 20 

In the similar way HERD is coded by writing place value of each alphabets at their corresponding places.

Use the same logic in CLOTH = 31215208

Option c is correct.

Q2. In a certain way , 'PING' is written as'4' and 'METAL' is written as '5'. Find the code for 'STEADYS'.

a. 8

b. 5

c.6

d.7

Sol- Logic = In the code just writing only total no. Of letters in the word.

so, in STEADYS = 7. option d is correct.

Q3. If    'DIG ' is coded as 25 and ' CUT' is coded as 49 then how will you code 'KICK'.

a. 43

b.39

c.41

d.34

Sol- Just thing the logic behind writing DIG  as 25 by using place value.

DIG = 4 + 9 +7 =20  but given 25 so just add 5 in the last after adding forward place value 

= 20 +5 = 25

Similarly,  CUT = 3 +21+20 =44 add 5 =49

KICK= 12 +9+3+12 =34 +5 =39 

Hence , option b correct. 

Q4. If the sentence ' mee muk pic' means 'roses are yellow' , 'nil dic' means ' white flowers' and 'pic mukarta dic' means ' flowers are fruits'. Find the code for ' White' in the same code language.

a  nil

b. Pic

c. dic

d.muk

Sol-  Just go for search that word only which you need to find it i.e., white.

Here code' White ' is present only in second sentence so, corresponding word should be unique I. E., only present in second sentence. Just check which word is unique out of two codes of nil and dic. We can easily find code dic are present in 2nd and 3rd sentence hence it is not unique so, we left with only one code 'nil' so, unique code is 'nil' so will be our final answer.

option a is correct.

Q5. 'EDITION' is written as ' VWRGRLM' then which word will be coded as ' SLMVHGB'?

a. HAUGHTY

b. AMNESTY

c. HONESTY

d. EDITORS

Sol- Logic simply writing  opposite letters of each alphabets present in the given word.

SLMVHGB = H O N E S T Y.

Q6. If AT =20 and BEG=70 then BANK=?

a. 308

b. 318

c. 228

d. 282

Sol- AT = 20

LOGIC - PLACE VALUE OF 'A' × PLACE VALUE OF 'T' = 1 × 20 

Similarly,  BEG = 2× 5×7 =70

BANK = 2 ×1 ×14×11= 308

Hence option a is correct.

Q7.If ' BANKER' = 'NABREK' 

           STRING = ?

a. RSTGIN

b. RTSGNI

c. TSIRGN

d. RTSGNI

Sol- Logic just reversed initial three letters and last three letters are reversed.

Hence option b is correct.

Q8. If A=4  and C =6 then code for 'Power'?.

a. 181726821

b. 191826821

c. 191825821

d. 181725720

Sol- Logic A =4  = place value of A (1) + 3 

Similarly C=6 = place value of C(3) +3 =6

so, power = 191826821

Option b correct 

Q9. If ' DRIVE' = 59372  and 'SPUR' = 6489 

Findex the code for 'PRIDE'?

a. 49235

b.94532

c.49352

d.43925

Sol- Logic check common lettersense in the given both code and it's corresponding code in both words, it should be same.

R =9 in both sentence so, it is clear that all corresponding codes have been written at their  corresponding letters .

So, PRIDE = 4 9 3 5 2

Hence option c correct.

Q10. If A = 1 , C = 3  and ABC = 6 then CAT =?

a. 24

b.23

c.20

d.19

Sol- Logic  is writing place value and add them. 

C  A T = C (3) + A (1) + T(20) = 24.

Hence , option a is correct.
