Question Discussion & Solution

The relation among the given numbers is:

1 × 2 = 2

2 % 3 = 2

2 × 4 = 8

8 % 5 = 3

3 × 6 = 18

18 % 7 = 4

4 × 8 = 32

32 % 9 = 5

(where ‘%’ is the modulo or the remainder operator.)

The correct answer is Shark — Tortoise — Otter.

Key Points

• Shark - Scientists believe that sharks came into existence around 400 million years ago. It is believed that they descended from a small leaf-shaped fish that had no eyes, bones on fins.
  • These fish then evolved into two main groups of fish that are found today.
  • Bony fish and cartilaginous fish which include shark and Chimaira.
  • Sharks are on the top of the marine food chain and are the only huge marine reptiles that exist today.
• Tortoise is believed to have existed for 250 million years.
  • They belong to the reptile species of the family Testudinidae.
  • Tortoise has a hard shell to protect from the outside environment. They are believed to have evolved from very large body sizes of around 100 kgs. They are among the longest-living land animals in the world.
• Otters are believed to have existed on earth for the past 23 million years.
  • They have evolved significantly and have gone through many adaptations to survive till this time.

Additional Information

• They have the ability to move both on water and land except sea otters. The rest of the otters have webbed feet which help them to move in the water.
• They have five toes which help them to move on land as well. It is believed that they were once land animals only but they ended up going in the water to be safe from predators.
• It is also believed that the food sources were available in limited quantities on land so they started hunting in water to survive.

The correct answer is Andhra Pradesh.

Key Points

• Indian Space Research Organization's Satish Dhawan Space Centre is located at Nellore District, Andhra Pradesh. 
• Satish Dhawan Space Centre (SDSC), Sriharikota, the Spaceport of  India, is responsible for providing Launch Base Infrastructure for the Indian  Space Programme.

Concept:

• Six Sigma is a statistical term used to measure the number of defects that processes create.
• The term implies high-quality performance because a process performing at a Six Sigma level allows only 3.4 defects per one million opportunities.

Different sigma levels of quality would lead to the following number of defects.

1. Three Sigma quality – This level of performance produces a defect-free product 93.32% of the time. 770 applications would be processed incorrectly and would require rework every day.
2. Four Sigma quality – This level of performance yields a defect-free product 99.349% of the time. With four sigma quality, 73 applications would need to be corrected every day.
3. Five Sigma quality – Five Sigma performance produces defect-free products and services 99.977% of the time. Every week the bank would need to correct 13 application errors.
4. Six Sigma quality – Six Sigma performance produces a defect-free product 99.99966% of the time; allowing only 3.4 errors per one million opportunities. 10 applications would need to be corrected during the entire year.

Important Points:

Four sigma and six sigma levels of performance both have an error free rate over 99% of the time. However, the large volume of applications in this example makes all of the difference. With numbers this big, it turned out that the four-sigma process made 18,710 more errors than the six sigma process.

The correct answer is Local Area Network.

• A Local Area Network (LAN) is a collection of devices connected together in one physical location, such as a building, office, or home.
• A LAN can be small or large, ranging from a home network with one user to an enterprise network with thousands of users.
• A LAN single defining characteristic is that it connects devices that are in a single, limited area.

Additional Information

• In contrast, a Wide Area Network (WAN) or Metropolitan Area Network (MAN) covers a larger geographical area.
• Some WANs and MANs connect many LANs together.
• Ethernet and Wi-fi are the two most common technologies in use for local area networks. Historical network technologies include ARCNET, Token ring, and Appletalk.
