The Danish World No.1 Viktor Axelsen clinched victory in the Japan Open final after defeating Jonatan Christie of Indonesia.
In women’s singles, world number two An Se-Young of South Korea beat He Bing Jiao of China to clinch the title. She also replaced replacing Japan’s reigning world champion Akane Yamaguchi to bag the World No. 1 spot.

Four friends W, X, Y and Z are students of Class 10th.

i) W and X are good in Hindi but poor in English.

ii) W and Y are good in Science but poor in Mathematics.

iii) Y and Z are good in English but poor in Social Studies.

iv) Z and X are good in Mathematics as well as in Science.

Thus we can see Y and Z pairs of friends are good, both in English and Science

Hence, the correct answer is "Y and Z".

Checking Statement I:

Since there is no data given about Player and Champion, therefore, No player is Champion can not be derived.

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

Checking Statement II:

Statement II is the converse statement of the required conclusion.

Clearly, Statement II alone is sufficient to answer the question.

Hence, Option B is correct.

यहाँ खाना काम एक ही है। सेब और केला एक साथ है।

Turning over a new leaf: start to act or behave in a better or more responsible way. This idiom fits in the given context of the sentence correctly.
Hit the ground running: start something and proceed at a fast pace with great enthusiasm. This idiom fits correctly in the sentence as well.
Hence, the correct answer is option B. 

The HIV is transmitted among humans through close and direct physical contact with infected bodily fluids, the most infectious being blood, faeces and vomit. The HIV has also been detected in breast milk, urine and semen. Nipah virus, SARS and Ebola virus are thought to be spread by fruits bats.

In nature, almost all metals are found in solid state except mercury. Mercury is a metal that is found in a fluid state at normal temperature.

English chemist John Dalton (1766-1844) first proposed the modern atomic theory. John Dalton's theory is called modern because all the facts written about the atom were experimentally found to be correct. It has mainly five parts.

The correct answer is the Presentation program.

Key Points

• Microsoft PowerPoint
  • It is a powerful slide show presentation program. Hence, Option 4 is correct.
  • It is a standard component of the company's Microsoft Office suite software and is bundled together with Word, Excel, and other office productivity tools.
  • The program uses slides to convey information rich in multimedia.

Additional Information

The correct answer is Worm.

Key Points

• A worm is a computer programme that can self-replicate and propagate over the network with or without human intervention and has malicious intent.
• Its purpose is to secretly duplicate itself into other computers.
• Unlike a computer virus, which "infects" other programmes in order to spread to new ones, worms are often self-contained programmes that do not require a "host."
• Worms typically do not require human intervention to spread across networks.
• Robert Morris, a computer science student at Cornell University, unleashed the first worm into the Internet from the Massachusetts Institute of Technology on November 2, 1988.
• Viruses and worms are a type of malicious software.
• Worms frequently take advantage of network configuration mistakes or security flaws in the operating system (OS) or applications.

Additional Information

• A kernel is computer software that runs at the core of the operating system and has complete control over all of the system's components.
• A Trojan Horse Virus is a sort of malware that disguises itself as a genuine programme and downloads into a computer.
• A computer virus is designed to spread from host to host and duplicate itself.

The correct answer is Calculator.

Key Points

• Calculator is an example of a fixed program computer.
  • A Fixed Program Computer is a special-purpose computer that has a program permanently wired in.
  • A desk calculator is a fixed program computer as it can do basic mathematics but cannot run a word processor or games.
  • In order to change the program of a fixed-program machine, requires rewiring, restructuring, or redesigning the machine.

Additional Information

• John Von Neumann proposed the Stored-Program Concept in the 1940s based on Alan Turing‘s Turing machine.
  • The idea was to store program instructions and data in the same memory.
  • These stored instructions are executed on the stored data that produces results.
  • These results are also stored in the same memory.
  • This concept made computers “re-programmable”. 

The correct answer is higher, high.

Key Points

• Dynamic RAM is a type of RAM that stores bits in small capacitors. In order to retain the data stored in it, it needs to be continually refreshed.
• It is widely used in digital electronics where low-cost, high-capacity memory is required.
• DRAM is cheaper as it only requires a single transistor compared to around six in a typical static RAM.
• DRAM has a high packaging density, it is slower as compared to SRAM as it has a higher access time.
• (SRAM has lower access time and is faster whereas DRAM has a higher access time and is slower compared to SRAM)

The Schottky also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action. A silicon diode has a typical forward voltage of 600–700 mV, while the Schottky's forward voltage is 150–450 mV. This lower forward voltage requirement allows higher switching speeds and better system efficiency.

The superposition theorem states that in any linear bilateral network that consisting of two or more independent sources, current through (or voltage across) an element is the algebraic sum of the currents through (voltages across) that element caused by each independent source acting alone with all other sources are replaced by their internal resistances.

Hence, the correct option is (A)

Most of the measurement systems contain three main functional elements are i) Primary sensing element ii) Variable conversion element & iii) Data presentation element. Primary sensing element: The quantity under measurement makes its first contact with the primary sensing element of a measurement system.

Hence, the correct option is (D)

The ratio of minimum fusing current and current rating of the fuse:

fusing factor = Minimum fusing current or current rating of the fuse.

The value of the fusing factor is always more than 1.

Hence, the correct option is (A)

.^.. T/2 = 2 x [10m]

⇒ T = 40 X 10^-3

f = 25Hz

Semiconductors which are chemically pure, meaning free of impurities, are called Intrinsic Semiconductors or Un doped Semiconductor or i-type Semiconductor. The most common intrinsic semiconductors are Silicon (Si) and Germanium (Ge), which belong to Group IV of the periodic table. The atomic numbers of Si and Ge are 14 and 32.

From equation (3) and (4)
