Given: "pu ma kas' means 'we eat mangoes'.

Statements: 

I. 'la ti kas' means 'we are graduate'.

II. 'hum tup pu' means 'they eat bananas'.

From I and II statements we conclude that both are sufficient to answer the question. So 'ma' is the code of 'mangoes'.

Hence, Statements I and II together are sufficient to answer the question.

Considering statement I alone:

I. In a certain code language, AIEEE is written as BJFFF.

Here logic is +1 in the Vowel

Therefore, the information given in statement I alone is not sufficient to answer the question.

Considering the statement II alone.

II. In a certain code language, GYPSY is written as FXORX.

Here logic is - 1 in the Consonant.

Therefore, the information given in statement II alone is also not sufficient to answer the question.

Now, by using both statements.

Here, code for PRODUCT is OQPCVBS

So, data in both statements I & II together are necessary to answer the question

Hence, the correct answer is "Option 4".

According to the question:

I) In a certain code language, “Fruits are rotten” is coded as “fgh spu myt” and “Sweet sour candy” is coded as “brd cwa pza”, “sour rotten grapes” is coded as “cwa spu alp” and “Fruits juicy sweet” is coded as “myt qmh brd”.

Here, code for 'grapes' is 'alp'. Therefore statement I alone is sufficient to answer the question.

II) In a certain code language, “Season of grapes” is coded as “alp dmb evb”, “Dry season fruits” is coded as “rex brd evb” and “dry mangoes pickle” is coded as “sap rex web”.

Here, code for 'grapes' can be either 'alp' or 'dmb'. Thus cannot be determined, therefore statement II alone is not sufficient to answer the question.

Thus, the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question.

Hence, "Option 1" is the correct answer.

Solution:

Considering statement I alone:

I. In a certain code language,

'no one with face' is coded as 'fo to om sop'

And 'no one has face' is coded as 'om sit fo sop'.

Here, 'no', 'one', and 'face' have common codes 'fo', 'om', and 'sop', but the exact mapping is unclear.

Therefore, the information given in statement I alone is not sufficient to answer the question.

Considering the statement II alone.

II. In a certain code language,

'face of no light' is coded as 'om mot fo kiz'

And 'no one is smart' is coded as 'sop fo sip lik'.

Here, 'face' and 'no' have common codes 'om' and 'fo', and 'no' has common codes 'fo' and 'sop', but the exact mapping is unclear.

Therefore, the information given in statement II alone is also not sufficient to answer the question.

Now, by using both statements.

Comparing both statements, 'no' is common and has codes 'fo' and 'sop'. 'face' is common and has codes 'om' and 'fo'.

From statement I, 'no one' is 'fo sop' or 'om sop'. From statement II, 'no one' is 'sop fo'.

Therefore, 'no' is 'fo'.

Since 'no' is 'fo', then 'face' must be 'om'.

So, data in both statements I & II together are necessary to answer the question.

Hence, the correct answer is "Option 4".

Question:

In a certain code language, 'fire in mountain' is coded as 'si ph bo'. What is code for 'fire'?

Statements:

(I) 'mountain' is coded as 'bo'.

(II) 'ice and fire' is coded as 'si yu ca'.

Solution:

Statement I:

'mountain' is coded as 'bo'.

This statement alone tells us the code for 'mountain' but does not provide enough information to determine the code for 'fire'.

Statement II:

'ice and fire' is coded as 'si yu ca'.

From the original statement, 'fire in mountain' is coded as 'si ph bo'.

Comparing the two statements, 'fire' is common in both. 'si' is common in both.

Therefore, 'fire' is coded as 'si'.

Conclusion:

Statement II alone is sufficient to answer the question, while Statement I is not.

Hence, the correct answer is 4) Data in Statement II alone is sufficient to answer the question while data in Statement I is not.

Using statement I:

I. In the code language, 'she walks fast' is written as 'he ka to'.

We can not determine the code for "walks".

Using statement II:

II. In the code language, 'she learns fast' is written as 'jo ka he'.

Using this statement we can not determine the code for "walks".

By combining statements I and II:

I. In the code language, 'she walks fast' is written as 'he ka to'.

II. In the code language, 'she learns fast' is written as 'jo ka he'.

The words 'she' and 'fast' are common in both sentences and so are the codes 'he' and 'ka'. Implies, 'he' and 'ka' are the codes for 'she' and 'fast' but not necessarily in the same order.

It further implies that 'to' is the code for the word 'walks' and both statements are required to answer the question.

Hence, "data in both statements I and II together are necessary to answer the question".

Given,

Question:
Identify the code for SUN from the given statements.
Statement:
I: GUN is written as HUN and TUN are written as UUN.
II: SUN rises from the east.

From statement I, we get,

GUN → HUN, TUN → UUN

The pattern followed here is,

Here we see we get the code from Statement I.

And statement II is irrelevant as it does not give the answer.

∴ The only statement I is sufficient.

Hence, the correct answer is the Only statement I is sufficient.

Pattern followed here is : ​

1. ​First letter → Shifted to the second position.
2. Second letter → Shifted to the fourth position. 
3. Third letter → No change.
4. Fourth letter → Shifted to the fifth position.
5. Fifth letter → Shifted to the first position.

According to the question :

• Statement - (1) : CHILE is coded as ECIHL.

​

Here, following the same pattern CHINA can be coded as 'ACHIN' i.e 

• Statement - (2) : EGYPT is coded as TEYGP.

​

Here, following the same pattern CHINA can be coded as 'ACHIN' i.e 

Thus, according to both the statements (1) and (2), code for CHINA is same with same pattern therefore, the question asked cab be answered from either statement (1) or statement (2).

Hence, "Option - (3)" is the correct answer.

According to the question :

• Statement - (1) : Blue is called pink, red is called orange and orange is called yellow

​So, from the given statement :-

Here, as colour of human blood is red thus according to the given information the answer will be orange.

• Statement - (2) : White is called black, black is called green, green is called brown and brown is called red.​

​So, from the given statement :-

Here,  as colour of human blood is red thus according to the given information there is no answer.

Thus, it is evident that only statement - (1) is sufficient to answer the given question while statement - (2) not.

Hence, "Option - (2)" is the correct answer.

1. "All are very beauty" means 'Ka Ta Pa Ra'

The code for 'good' cannot be obtained from the above statement as 'good' is not present in it.

2. "They are good" means Ya Ra Sa

The code for 'good' cannot be obtained from the above statement as the code for other words and 'good' are not specifically mentioned.

By combining statement I and II:

The code for good may be Ya or Sa.

So, The facts of both statements 1 and 2 together are not sufficient to answer the question.

Given: "pu ma kas' means 'we eat mangoes'.

Statements: 

I. 'la ti kas' means 'we are graduate'.

II. 'hum tup pu' means 'they eat bananas'.

From I and II statements we conclude that both are sufficient to answer the question. So 'ma' is the code of 'mangoes'.

Hence, Statements I and II together are sufficient to answer the question.

The code for 'give' is 'De'.

Hence, Statements 1 and 2 together are required to tell the answer.

Word “clear” is common in both Statement I and II. So from that, we can easily say that the code of “clear” is “ru”.

So, the code of “clear” will be “ru”.

Hence, ‘Only I and II are sufficient’ is the correct answer.

On combining statement I and II:

1. "I love Mangoes" is written as 'E la mange'.

• Here, there are 3 possible codes for "Mangoes" - E or la or mange. Therefore, statement 1 alone is not sufficient and option 1 is wrong.

2. 'I love Orange' is written as 'E la orage'.

• No information is given about the code of "Mangoes". Therefore, statement 2 alone is not sufficient and option 4 is wrong.

• From statements 1 and 2, we get the following:
• 
• Therefore, the code of "Mangoes" is "mange".
• So, statements 1 and 2 together are sufficient.

Hence, "option 3" is the correct answer.
