ANS:B - Only argument II is strong

Explanation: Income -tax is levied so that every citizen can contribute a share of his earning towards the infrastructural development of the nation. So, argument I seems to be vague. However, income-tax is no doubt a good source of revenue for the government. Hence, argument II holds strong.

ANS:C - Petrol

Among the options listed, Petrol (Gasoline) typically has the maximum °API gravity of all. Here's why:

• °API Gravity: API (American Petroleum Institute) gravity is a measure of how heavy or light a petroleum liquid is compared to water. Higher API gravity values indicate lighter and less dense liquids.
• Petrol (Gasoline): Gasoline has a higher °API gravity compared to diesel, kerosene, and furnace oil. Gasoline is refined to be lighter and more volatile, with a higher proportion of lighter hydrocarbons, which results in a higher °API gravity.
• Comparison with Other Options:
  • Diesel: Diesel has a lower °API gravity than gasoline because it contains heavier hydrocarbons.
  • Kerosene: Kerosene also has a lower °API gravity than gasoline. It is typically less volatile and lighter than diesel but heavier than gasoline.
  • Furnace Oil: Furnace oil (also known as fuel oil) generally has the lowest °API gravity among these options. It consists of heavier, more viscous hydrocarbons compared to gasoline, diesel, and kerosene.

ANS:C - India

The UN General Assembly president is visiting India from January 29-31.

ANS:A - 2

Structure of the Problem:

Explanation of the Pattern:

Sequence of Sums:

• The sequence of sums follows this pattern: 5, 10, 15, 20, 15, 10, 5.

Step-by-Step Process:

1. Calculate the Sum for Each Row:
   • For each row, add up all the numbers.
2. Identify the Sequence:
   • The sum of the first row is 5.
   • The sum of the second row is 10.
   • The sum of the third row is 15.
   • The sum of the fourth row is 20.
   • After reaching 20, the sequence begins to decrease:
     • The sum of the fifth row is 15.
     • The sum of the sixth row is 10.
     • The sum of the seventh row is 5.

Example Walkthrough:

• Row 1: Sum = 5
• Row 2: Sum = 10
• Row 3: Sum = 15
• Row 4: Sum = 20
• Row 5: Sum = 15
• Row 6: Sum = 10
• Row 7: Sum = 5

Conclusion:

ANS:C - 9

Structure of the Problem:

Explanation of the Pattern:

Step-by-Step Process:

1. Identify the Three Numbers on the Triangle:
   • Look at the numbers placed at each of the three vertices of the triangle.
2. Determine the Two Smaller Numbers:
   • Out of the three numbers, identify the two smaller ones.
3. Calculate the Sum:
   • Add these two smaller numbers together.
4. Check Against the Third Number:
   • The result of this addition should equal the third number, which is the largest of the three.

Example Walkthrough:

• Vertices: 3, 6, and 9

Calculation:

1. Identify the Two Smaller Numbers:
   • The two smaller numbers here are 3 and 6.
2. Sum of the Smaller Numbers: 3+6=93 + 6 = 93+6=9
3. Check the Third Number:
   • The sum of 3 and 6 equals 9, which is the third number.

Conclusion:

ANS:A - 6

Structure of the Problem:

Explanation of the Pattern:

Step-by-Step Process:

1. Identify the Five Surrounding Numbers:
   • Look at the five numbers placed around the star.
2. Calculate the Average:
   • Add up all five surrounding numbers.
   • Divide the sum by 5 to get the average.
3. Determine the Central Number:
   • The central number should be equal to the calculated average of the surrounding numbers.

Example Walkthrough:

• Surrounding Numbers: 4, 5, 7, 6, 8

Calculation:

1. Sum of the Surrounding Numbers: 4+5+7+6+8=304 + 5 + 7 + 6 + 8 = 304+5+7+6+8=30
2. Calculate the Average: Average=305=6\text{Average} = \frac{30}{5} = 6Average=530​=6
3. Central Number:
   • The central number is 6, which matches the calculated average.

Conclusion:
