Detailed Solution for SCI Junior Court Assistant Mock Test- 4 - Question 15

Given:

Balance for the first 24 days = Rs. 5,600

Balance for the next 2 days = Rs. 12,000

Balance for the last 4 days = Rs. 37,500

Formula Used:

Average balance = Total balance for the month / Number of days in the month

Calculation:

Total balance for the first 24 days = 24 × Rs. 5,600

Total balance for the next 2 days = 2 × Rs. 12,000

Total balance for the last 4 days = 4 × Rs. 37,500

Total balance for the month ⇒ (24 × 5600) + (2 × 12000) + (4 × 37500)

Total balance for the month ⇒ 134400 + 24000 + 150000

Total balance for the month ⇒ 308400

Number of days in April = 30

Average balance = 308400 / 30

Average balance = Rs. 10,280

The daily average balance for April is Rs. 10,280.

SCI Junior Court Assistant Mock Test- 4 - Question 16
A mixture worth Rs. 3.25 a kg is formed by mixing two types of rice, one costing Rs. 3.10 per kg and the other Rs. 3.60 per kg. In what proportion must they have been mixed?
Detailed Solution for SCI Junior Court Assistant Mock Test- 4 - Question 16

Given:

A mixture worth Rs. 3.25 a kg is formed by mixing two types of rice, one costing Rs. 3.10 per kg and the other Rs. 3.60 per kg.

Calculation:

Let P kg of rice that costs Rs. 3.10 per kg be mixed with Q kg of rice that costs Rs. 3.60 per kg.

Total price of P kg rice = 3.10 × P = Rs. 3.10P

Total price of Q kg rice = 3.60 × Q = Rs. 3.60Q

Total price of the mixture = Rs. {(P + Q) × 3.25}

According to the question,

(P + Q) × 3.25 = 3.10P + 3.60Q

⇒ 3.25P + 3.25Q = 3.10P + 3.60Q

⇒ 3.25P - 3.10P = 3.60Q - 3.25Q

⇒ 0.15P = 0.35Q

⇒ 15P = 35Q

⇒ P/Q = 35/15

⇒ P/Q = 7/3

⇒ P : Q = 7 : 3

In 7 : 3 they must have been mixed.

SCI Junior Court Assistant Mock Test- 4 - Question 17
A train 100 m long is running at a speed of 70 km per hour. In how much time will it pass a man who is running at 10 km per hour in the same direction in which the train is going?
Detailed Solution for SCI Junior Court Assistant Mock Test- 4 - Question 17

Given:

Train length = 100 m

Speed of the train = 70 kmph

Speed of the person = 10 kmph

Concept used:

While a train crosses a person, it crosses its own length.

Relative speed is the difference between their individual speeds while two objects are running in the same direction.

Time × Speed = Distance

1m/s = 18/5 km/h

Calculation:

70 km/hr = 70 ÷ (18/5) = 175/9 meter per second

10 km/hr = 10 ÷ (18/5) = 25/9 meter per second

The relative speed of the train

⇒ 175/9 - 25/9

⇒ 150/9 meter per second

Now, time taken by the train to pass the man

⇒ 100 ÷ (150/9)

⇒ 6 seconds

∴ The train will pass the man in 6 seconds.

System software acts as a bridge between the hardware and _____ software?
Detailed Solution for SCI Junior Court Assistant Mock Test- 4 - Question 28

The correct answer is Application

Explanation

  • An application, or application program, is a software program that runs on your computer. Web browsers, e-mail programs, word processors, games, and utilities are all applications. The word "application" is used because each program has a specific application for the user.
  • In contrast, system software consists of programs that run in the background, enabling applications to run. These programs include assemblers, compilers, file management tools, and the operating system itself. Applications are said to run on top of the system software since the system software is made of "low-level" programs. While system software is automatically installed with the operating system, you can choose which applications you want to install and run on your computer.
  • Macintosh programs are typically called applications, while Windows programs are often referred to as executable files. This is why Mac programs use .APP file extension, while Windows programs use the .EXE extension. Though they have different file extensions, Macintosh and Windows programs serve the same purpose and can both be called applications.

  • Trojans
    • Trojans disguise themselves as legitimate software to trick users into installing them.
    • Once installed, Trojans can create backdoors, steal data, or install additional malware.
    • They do not replicate like viruses but can cause significant damage by providing unauthorized access to attackers.
