UPSSSC JE Mechanical Paper 1 Mock Test - 3 - Mechanical Engineering MCQ

स्त्रीलिंग परिवर्तन का सही विकल्प ‘गुणवती-गुणवान’ होता है। अतः इसका सही उत्तर विकल्प 1 ‘गुणवती-गुणवान’ होगा। अन्य विकल्प सही उत्तर नहीं हैं।
Confusion Points

• राज्ञा-राजा यह युग्म गलत है, इसका शुद्ध रूप रानी - राजा होना चाहिए।
• बुद्धिमती-बुद्धिमत्त यह युग्म गलत है, इसका शुद्ध रूप बुद्धिमती- बुद्धिमान होना चाहिए।

स्पष्टीकरण:

जिन पुल्लिंग शब्दों के अंत में ‘वान’ आता है उनका परिवर्तन स्त्रीलिंग में करने के लिए ‘वती’ शब्द जोड़ दिया जाता है।

जो शब्द अन्य शब्दों के योग से बनते हो, परन्तु एक विशेष अर्थ के लिए प्रसिद्ध होते है, उन्हें योगरूढ़ शब्द कहते है।

जैसे- लम्बोदर, पंकज, दशानन, जलज इत्यादि।

लम्बोदर = लम्ब +उदर

(बड़े पेट वाला )= गणेश जी

दशानन = दश +आनन

दस मुखों वाला = रावण

'पंक +ज' अर्थ है कीचड़ से (में) उत्पत्र; पर इससे केवल 'कमल' का अर्थ लिया जायेगा, अतः 'पंकज 'योगरूढ़ है।

The correct answer is 'strike'.

Key Points

• The passage is a non-fiction piece on the theme of 'freedom'. The purpose of this passage is to explain, analyse, define or clarify something—to provide us with information and to show the how and why of things.
• Read the lines of the passage- "Your only remedy at present is the Trade Union Weapon of the strike which is only the old Oriental device of starving on your enemy’s doorstep until he does you justice. "
• After reading the above lines from the passage we can conclude that the only remedy available to the workers to get their demands fulfilled is strike.

Therefore, the correct answer is Option 2.

• 'थाली में छेदं करना' एक मुहावरे है जिसका अर्थ है जिस व्यक्ति के आश्रय में रहना, उसी को हानि पहुंचाना।
• 'आँखे खुलना' मुहावरे का अर्थ बुरा समय आते ही सचेत हो जाना चाहिए या सावधान होना।

Additional Information

• मुहावरा- ऐेसे वाक्यांश या पदबंध जो अपना सामान्य अर्थ का बोध न कराकर विशेष या विलक्षण अर्थ का बोध कराते है।
• जैसे 'अढाई दिन की बादशाहत' का अर्थ थोड़े दिन की शान-शौकत।
• 'अंतड़ियों में बल पड़ना'- पेट में दर्द होना।
• '​एक तंदुरुस्ती हजार नियामत'-स्वास्थय बहुत बड़ी चीज है।

The correct answer is They will have repaired all the roads before the monsoon season.

Key Points

• The structures for both the active and passive forms for future perfect tense are given below:
  • Active form- Subject + shall/will + have + V3 + Object
  • Passive form- Object + shall/will + have been + V3 + by + subject

• Example:
  • She will have played football. (active)
  • Football will have been played by her. (passive)
• Following this structure in active voice form, we get the 4th option as the correct answer.

Following these steps, we get- They will have repaired all the roads before the monsoon season.
Additional Information ​​​​

• The passive voice is not possible for the following tenses as the auxiliary verb 'be' can't be used together twice:
• ​Modal continuous tense
  • Example: I should be helping others more often.
• Future continuous tense
  • Example: I will be visiting Agra soon.

Checking Statement I:
Using the above references, we get the following arrangement:

Since there is no information about the position of Bhanu so we cannot find the person who sits on the immediate right of Bhanu.

Hence, data in statement I alone is not sufficient.
Checking Statement II:
Using the above references, we get the following arrangement:

Clearly, Prakash sits on the immediate right of Bhanu.

Hence, data in statement II alone is sufficient.

Hence, Option B is correct.

24 → 2 x 4 = 8

32 → 3 x 2 = 6

As on melting, liquid is formed similarly on freezing solid is formed.

From the final arrangement, we get “Q sits second to the right of the one who sits immediate left of M.
Hence, Option C is correct.
References:
O sits 3^rd to the right of N.
One who sits just behind O is to the immediate right of E.
Inferences:
From the above reference, we get the following cases:

References:
B is neither at any of the extreme ends nor sits exactly behind O.
The number of people sitting between C and E, is the same as the number of people sitting between E and B.
Inferences:
From the above reference, we get the following cases:

References:
D doesn’t sit at any of the extreme ends.
P sits on a seat which is exactly ahead of A.
M is not exactly ahead of E.
Inferences:
From the above reference, we get the following cases:
Case 1: Position of D cannot be fixed, thus this case is eliminated.
​​​​​​​
Case 2: We get the final arrangement as below:

As 'smoke' leads to 'pollution' in the same way ''War'' leads to 'destruction'.

Creating a Vertical Page Break

• Answer: C

When creating a vertical page break in Excel, the active cell must be in row 1. This means that the active cell must be located within the first row of the worksheet.

Explanation:

• The active cell refers to the cell that is currently selected or highlighted in Excel.


• A vertical page break is used to specify where a new page should begin when printing a worksheet.


• To create a vertical page break, the active cell must be in row 1, as specified in option C.

Here are the details for each option:

• Option A: The active cell must be A1




• This option is incorrect because the active cell does not need to be specifically A1 when creating a vertical page break.




• Option B: The active cell can be anywhere in the worksheet




• This option is incorrect because the active cell must be in row 1, not anywhere in the worksheet.




• Option C: The active cell must be in row 1




• This option is correct. When creating a vertical page break, the active cell must be located within the first row of the worksheet.




• Option D: The active cell must be in column A




• This option is incorrect. While the active cell must be in row 1, it does not need to be in column A specifically.

Overall, when creating a vertical page break in Excel, it is important to have the active cell in row 1 as stated in option C. This ensures that the page break is correctly applied to the worksheet when printing.

The correct answer is ​Program Unit.

• A program unit is a sequence of one or more lines, organized as statements, comments, and directives. A subprogram is either a function or a subroutine and is either an internal, external, or module subprogram.
• A program unit is usually a sequence of statements that define the data environment and the steps necessary to perform calculations; it is terminated by an END statement.

Additional Information 

• A Fortran program consists of one or more program units.
• Alternately referred to as a processor, central processor, or microprocessor, the CPU (pronounced sea-pea-you) is the central processing unit of the computer.
• A computer's CPU handles all instructions it receives from hardware and software running on the computer. It is often referred to as the brain of the computer.
• Components of CPU:
  • ALU (arithmetic logic unit) - performs mathematical, logical, and decision operations.
  • CU (control unit) - directs all the processor's operations.
  • Storage Unit.

User-level threads are very effective because a mode switch is not required to switch from one thread to another. Here is a detailed explanation:

• Definition: User-level threads are managed by the application without the intervention of the operating system. They are created and scheduled by the application itself.


• Advantages: User-level threads offer several advantages, including:




• No mode switch: User-level threads do not require a mode switch from user mode to kernel mode when switching between threads. This makes the context switch faster and more efficient.


• Thread management control: The application has full control over thread management, including scheduling, synchronization, and resource allocation.


• Portability: User-level threads can be easily ported across different operating systems, as they are independent of the underlying kernel.




• Disadvantages: User-level threads also have some limitations:




• Blocking system calls: If a user-level thread performs a blocking system call, it will block the entire process, as the kernel is unaware of the individual threads.


• Limited parallelism: User-level threads may not fully utilize the available hardware resources, as the operating system schedules threads at the process level rather than at the thread level.

In conclusion, user-level threads are very effective because they eliminate the need for a mode switch and provide greater control over thread management. However, they also have some limitations that need to be considered in certain scenarios.
