ANS:B - Only argument II is strong

Explanation: Abolishing the import duty on electronic goods shall reduce the costs of imported goods and adversely affect the sale of the domestic products, thus giving a setback to the Indian electronics industry. So, argument II holds strong. Argument I does not provide a convincing reason.

ANS:D - unleaded motor fuels.

Research Octane Number (RON) refers to high octane number motor fuels. Here's an explanation:

• Research Octane Number (RON): RON is a measure of the resistance of a fuel to knocking combustion in internal combustion engines. It is determined under controlled laboratory conditions using a standardized test engine. Higher RON values indicate fuels that are more resistant to knocking, which is undesirable in gasoline engines.
• High Octane Number Motor Fuels: RON values are used to classify motor fuels based on their ability to resist knocking. Motor fuels with higher RON values are considered high octane number fuels. These fuels are suitable for use in high-performance engines and in applications where engine efficiency and performance under high load conditions are crucial.
• Comparison with Other Options:
  • Low Octane Number Motor Fuels: These fuels would have lower RON values and are more prone to knocking in engines.
  • High Octane Number Aviation Fuels: Aviation fuels (such as avgas) have different octane rating systems (e.g., Aviation Gasoline Octane Rating), not RON specifically.
  • Unleaded Motor Fuels: Unleaded fuels can have varying RON values depending on their composition and intended use, but RON itself specifically refers to the resistance to knocking.

ANS:C - Brazil

Brazil declared a medical emergency in the Yanomami territory.

ANS:B - 4

Structure of the Pattern:

1. Grid Layout:
   • The grid is arranged in rows, each containing a series of digits.
2. Sum Calculation:
   • The sum of the digits in each row follows a specific pattern as you move down the grid.

Explanation of the Pattern:

1. Sum of Digits:
   • For each row, calculate the sum of the digits in that row.
2. Increasing Sum:
   • As you move from the top row to the bottom row, the sum of the digits in each row increases by a constant amount.

Step-by-Step Process:

1. Calculate Row Sums:
   • Compute the sum of digits for each row.
2. Identify Increment:
   • Check how the sum increases as you move from the top to the bottom of the grid.

Example Walkthrough:

• Grid: 233444664\begin{matrix} 2 & 3 & 3 \\ 4 & 4 & 4 \\ 6 & 6 & 4 \\ \end{matrix}246​346​344​

Calculate Row Sums:

1. Top Row:
   • Sum = 2+3+3=82 + 3 + 3 = 82+3+3=8
2. Middle Row:
   • Sum = 4+4+4=124 + 4 + 4 = 124+4+4=12
3. Bottom Row:
   • Sum = 6+6+4=166 + 6 + 4 = 166+6+4=16

Check Increment:

• Increment from Top to Middle:
  • Difference = 12−8=412 - 8 = 412−8=4
• Increment from Middle to Bottom:
  • Difference = 16−12=416 - 12 = 416−12=4

Structure of the Pattern:

1. Triangles Configuration:
   • The diagram includes three triangles arranged in a circular pattern.
   • Each triangle has an outer set of digits and a central digit.
2. Sum Calculation:
   • Calculate the sum of the outer digits for each triangle.
   • Place this sum in the central position of the triangle that is one place clockwise in the arrangement.

Explanation of the Pattern:

1. Identify Outer Digits:
   • For each triangle, determine the digits located on the outer edges.
2. Calculate the Sum:
   • Add the outer digits together for each triangle.
3. Place the Sum:
   • Write the sum in the center of the triangle that is located one place clockwise from the current triangle.

Step-by-Step Process:

1. Find Outer Digits:
   • Identify the digits on the outer edges of each triangle.
2. Compute the Sum:
   • Calculate the total of these outer digits for each triangle.
3. Write the Sum:
   • Move one place clockwise and place the calculated sum in the center of the triangle in that position.

Example Walkthrough:

• Triangle A:
  • Outer Digits: 1, 4, 2
  • Sum = 1+4+2=71 + 4 + 2 = 71+4+2=7
• Triangle B:
  • Outer Digits: 3, 5, 1
  • Sum = 3+5+1=93 + 5 + 1 = 93+5+1=9
• Triangle C:
  • Outer Digits: 6, 2, 3
  • Sum = 6+2+3=116 + 2 + 3 = 116+2+3=11

Applying the Pattern:

1. Write Sums:
   • Place the sum of the outer digits of Triangle A (7) in the center of Triangle B.
   • Place the sum of the outer digits of Triangle B (9) in the center of Triangle C.
   • Place the sum of the outer digits of Triangle C (11) in the center of Triangle A.
2. Result:
   • The central digit of Triangle B will be 9, based on the sum of the outer digits of Triangle C.

Structure of the Pattern:

1. Sequence of Square Numbers:
   • The sequence starts with square numbers. The first six square numbers are 12,22,32,42,52,1^2, 2^2, 3^2, 4^2, 5^2,12,22,32,42,52, and 626^262.
2. Multiply Each Square Number by 2:
   • Each square number in the sequence is then multiplied by 2.

Explanation of the Pattern:

1. Identify Square Numbers:
   • List the first six square numbers: 12=11^2 = 112=1, 22=42^2 = 422=4, 32=93^2 = 932=9, 42=164^2 = 1642=16, 52=255^2 = 2552=25, and 62=366^2 = 3662=36.
