Question Discussion & Solution

The correct answer is 10.4%.

• Rajasthan is spread over approximately 10.4%  .
  • The state covers an area of 342,239 square kilometres.

​Additional Information

• Geography of Rajasthan
  • It is the largest Indian state by area and the seventh-largest by population.
  • Rajasthan is located on the northwestern side of India, where it comprises most of the wide and inhospitable Thar Desert (also known as the "Great Indian Desert") and shares a border with the Pakistani provinces of Punjab to the northwest and Sindh to the west, along the Sutlej-Indus river valley.
  • It is bordered by five other Indian states: Punjab to the north; Haryana and Uttar Pradesh to the northeast; Madhya Pradesh to the southeast; and Gujarat to the southwest.
  • Its geographical location is 23.3 to 30.12 North latitude and 69.30 to 78.17 East longitude.
  • The Tropic of Cancer passes through the southernmost tip of the state.

Let the three consecutive numbers be x, x + 1, x + 2

⇒ x + (x + 1) + (x + 2) = 345

⇒ 3x + 3 = 345

⇒ 3x = 345 – 3 = 342

\(\Rightarrow x = \frac{{342}}{3} = 114\)

So the three consecutive numbers are 114, 115 and 116. And the middle number is 115.

The logic is,

In the first image, there are six lines in the first column and there is a four-sided figure in the second column.

In the second image, there are eight lines in the first column and there is a six-sided figure in the second column.

So, it means that the number of sides of a figure in the second column is decreasing by two from the number of lines in the first column.

Since, in third image there are five lines so the answer figure must be a three-sided figure.

Thus, the correct figure is as follows:

The correct answer is OMR.

Important Points

• Optical mark recognition
  • It is the input device used to scan a marked answer book of a multiple choice question paper.
  • An optical answer sheet or bubble sheet is a special type of form used in multiple-choice question examinations. 
  • Optical mark recognition is used to detect answers.

Additional Information

• OCR
  • ​OCR (Optical Character Recognition) recognizes all the characters from the paper document.
  • It collects and stores them into an editable document.
• ​MICR
  • ​The term magnetic ink character recognition (MICR) refers to the line of numbers that appears at the bottom of a check.
  • The MICR line is a group of three numbers, which are the check number, account number, and bank routing number.
• Card reader
  • A card reader is a data input device that reads data from a card-shaped storage medium.

The pattern is:

31

31 × 2 + 1 = 63;

63 × 2 - 2 = 124;

124 × 2 + 3 = 251;

251 × 2 - 4 = 498

Hence, the answer is '498'.
