The least possible Venn diagram for the given statements is as follows-

Conclusions:

I. All Stylus can be Tablet → False (As some Stylus are Laptop and no Laptop are Tablet, so that Stylus which are Laptop will never be Tablet)

II. No Tablet is Phone → True (As ‘All phones are laptops’ and ‘No Laptop is Tablet’)

Hence, only conclusion II follows.

The least possible Venn diagram for the given statements is as follows

Conclusions:

I. All roses can never be green → True (All roses are blue and no blue is a green, so rose can never be green)

II. Some white can be blue → True (This is a possibility which can be true as shown below)

Hence, both conclusion I and II follow.

Additional Information:

1. Only a few green are white. → Some green are white + Some green are not white.
2. The word 'can be' depicts possibility.

The least possible Venn diagram for the given statements is as follows

Conclusions:

I. Some lines being road is a possibility → True (Possibility is true as shown below)

II. No map is a line → False (It is a possibility but not definite)

Hence, only conclusion I follows.

If we replace the first and third letters of each word with the letters which come immediately before and after them respectively in the English alphabet, then the words formed are as follows:

VET → UEU

CLA → BLB

XAW → WAX

DAS → CAT

NAS → MAT

Of these words, WAX, CAT, and MAT are meaningful.

Hence, three meaningful words are formed.

From the given information it can be clearly seen that at first the first and the third letters are interchanged, and after that, the first and second letters are interchanged.

Let us consider “123” as a word containing three letters.

Now, if we interchange the first and the third letter, we get “321”.

Again, if we interchange the first and the second letters in the word “321”, we get a new word i.e. “231”.

So, this is the ultimate operation that we have to apply over the given words and as a result, we get:

VET → ETV

CLA → LAC

XAW → AWX

DAS → ASD

NAS → ASN

Thus, we can see that ETV, AWX, ASD, and ASN are the four words that start with a vowel.

Hence, there are four words that start with a vowel.

If we arrange the given words in alphabetical order according to the English dictionary from left to right, we get:

Left End CLA   DAS  NAS  VET  XAW Right End

Hence, VET is the word that is at the second place from the right end after rearrangement.

If the second and the third letters are interchanged within the given words, then we have:

VET → VTE

CLA → CAL

XAW → XWA

DAS → DSA

NAS → NSA

Thus, CAL is the only word that does not end with a vowel.

Hence, only one will not end with a vowel.

If the given words are arranged in reverse dictionary order from left to right, then we get the words as follows:

Left End XAW  VET  NAS  DAS  CLA Right End

Second letter from the left end → A

Second letter from the right end → L

The letters in the English alphabet that come in between A and L are B, C, D, E, F, G, H, I, J, K.

Hence, there are ten letters between A and L.

Hence, the third letter is E.

Mistake Points

• HENT is a word that is no longer in use. So, it should not be considered.

According to the given information,

1. Four people are sitting between C and T. 2. Five people are sitting between E and C. 3. K is sitting second to the right of E. 4. T is sitting exactly between O and V, who is sitting third to the right of C. 5. Only three persons are sitting to the left of K and O is sitting second to the left of I. Here the case (i) - A, case (ii) - A and case (ii) - B gets eliminated as it is given that only three people sit to the left of K.

Hence, Seventeen is the correct answer.

1. Four people are sitting between C and T. 2. Five people are sitting between E and C. 3. K is sitting second to the right of E. 4. T is sitting exactly between O and V, who is sitting third to the right of C. 5. Only three persons are sitting to the left of K and O is sitting second to the left of I. Here the case (i) - A, case (ii) - A and case (ii) - B gets eliminated as it is given that only three people sit to the left of K.

 

Hence, T is the correct answer.

Hence, Eight is the correct answer.

Given: Six events, A, B, C, D, E, and F take place on two different dates, 7^th and 22^nd, of three different months, August, September, and October. 

Based on the given conditions, we get the following possibilities:

1. Event D takes place in the month of September. Event C is the last event to take place.

Combining these, we get-

 

2. Event F takes place on the first available date in the month of September. 

This eliminates Case 1 from above and we get-

 

3. Event A doesn't take place in the month of August. 

From this, we get-

 

4. Event B takes place immediately after event E. 

From this we get the final arrangement as follows-

 

Therefore, from the above arrangement, we see that event E is the first event to take place. 

Hence, event E is the first event to take place.
