Computer Science And IT (CS/IT) Mock Test For Gate - Computer Science Engineering (CSE) MCQ

The error lies in part (A) of the sentence as the pronoun ‘him’ is incorrect and must be replaced with a reflexive pronoun ‘himself’ which is used as the object of a verb or preposition to refer to a male person or animal previously mentioned as the subject of the clause.

Total possible outcomes  = ²⁷C₂

Favourable outcomes = Selecting any two authors × selecting one book for each author=

Let us take material cost and labor cost as Rs 300 and Rs 100 respectively. Since labor cost went up by 20%, the revised labor cost is Rs 120. The revised material cost due to 15% increase is Rs (300+15% of 300) = 345. The ratio of labor cost and material cost is 120: 345 or 8: 23 i.e. (b)

You have to carefully observe the point that in the last minute, we DO NOT have to consider the sliding down of the monkey since the question states that the monkey reaches the top of the tree.Out of 58 minutes, the climb by monkey in 58th minute is 3 feet whereas for each of his earlier climbs, the monkey covers a net distance of 3-1.5=1.5  feet.We can work out the maximum possible height of the tree as 1.5×57+3=85.5+3=88.5 feet

The error lies in the first part of the sentence where the verb ‘were’ is incorrect and needs to be replaced with ‘was’ as the subject "misuse" is singular. To make the subject and the verb agree it should read as:’The misuse of drugs and alcohol was seen as..’

Let Xi denote the ith dice.

Since events are independent,

E(xi) = 7/2

V(xi) = 350/12

According to Central Limit Theorem,

P(30≤ X ≤40) = P(30 – 35 ≤ X – 35 ≤ 40-35)

Its converting to standard form, X – E[X] / std, where std is standard deviation.

Thus,

P = 2N(1.0184) – 1

= 0.69

Migration is the only word which comes to the meaning of the word ‘exodus.’

Let's understand the meanings of each phrasal verb given in the options:

Broke off = became separated/detached

Broke out = started/began suddenly

Broke in = force entry to a building

Broke down = suddenly ceased or stopped to function (of a machine or motor vehicle)

As per the context of the sentence, the correct phrasal verb is "broke down".

Since we are given time to cross a point which is 1/5th of the way and 1/3rd of the way, we can rewrite them as 3/15th and 5/15th of the way which implies that 2/15th of the way was covered in 10 minutes.
This means that the entire route was covered in 10 × 15/2 = 75 minutes (each 1/15th part is covered in 75/15 = 5 minutes) leading to time of arrival at school as 9:50 – 15 + 75 = 10:50 hours.

Literal = line for line, letter to letter
Verbatim = in exactly the same words; word for word
Formal = conventional, traditional
Idealistic = visionary, dreamy, unrealistic
Outdated = out of date, obsolete
Hence, "Verbatim" best expresses the meaning of the word "Literal".

A basic block can end in any of the following:Jump statementConditional/ unconditional branchReturn statement

The like operator is used in the string to search for characters. Eg: All names starting with ‘A’ (select name from ABC were name like ‘A%’;) while where is used to check for the condition.

The logic pumping lemma is a good example of the pigeon whole principle.

Relative: 302 + 400 = 702

A file system is said to exhibit data dependence because a change in any file’s structure, such as addition or deletion of a field, requires modifications of all programs using that file. That means, access to a file is dependent on its structure.
A file system is said to exhibit data dependence because a change in any file’s data characteristics, such as changing the filed from integer to decimal, requires change in all data access programs. That means, access to a file data is dependent on its data characteristics.

If variables are declared previously, then semantic analyzer is responsible for generation of symbol table.

If variables are not declared, then lexical analyzer will generate the symbol table.

Hence option b is correct.

So, the insertion is followed in the same order, hence, we will insert 10 first which doesn’t effect the tree. Now, we insert 19. After insertion of 19 max_heapify founds an error in the node 17 → 11, 17 → 19. So, 19 is send up and 17 is brought down. After that the level order traversal changes to 30, 18, 19, 12, 11, 10, 17

Following is the syntax for creating views.

CREATEVIEW view_name AS

SELECT column_name(s)

FROM table_name

WHERE condition

Backslash actually acts an escape character and helps to print double quotes, where % can be printed only with double % i.e. %%

For this purpose, we can ignore the below forty numbers and have an array of 60 index to store the individual frequencies from 40 to 100.

given

now, the random variable X does represent number of throws required for getting 3. So,

The SUBI instruction, means the subtraction is in immediate addressing mode.

The given sequence is <1, a¹, a², a³, a⁴, ………..>.

The generating function for this sequence will be;

The only generating sequence that matching the above sequence is of option D

since , we know that 

Since we know that

As it is clearly mentioned that each team at least require one player so one team can acquire n number of athletes where n>=1. And also one athlete can play for more than one team i.e for m teams. So maximum cardinality is m:n

To check LL(1) we have to use some rules :
i. First(A1) ∩ First(A2) ∩ ...... ∩ First(An) = Ø
Where , A -> A1 | A2 | A3 ...... | An
ii. If any production contains null then do as follow
First(Ai) ∩ Follow(Ai) = Ø
If the above two rules satisfy then given grammar is LL(1) , but as per grammar given in question it is not satisfying above rule in production of B [ First(B) ∩ Follow(B) != Ø ].
To check LR(0) when we draw DFA for each item in Goto and Clousre , there is shift and reduce conflict.
Same case is with SLR(1) , in production B , there is shift reduce conflict.

We don’t need to calculate the final result, just calculate the unit digit raised to the power of unit digit of power of each term and add it. So,  1+7-3=5

In the above example food items are generalized on the basis that they all belong to fast food.
