Correct Answer: Bushfire have created havoc

Solution : The first option is correct.

In this part of the sentence, bushfire is a singular noun, but have is a plural verb, so they don't agree in number.

According to the subject-verb agreement, if the subject is plural, the verb must be plural. Conversely, if the subject is singular, the verb must be singular.

Therefore, the correct sentence will be: Bushfires have created havoc and exacerbated the conditions of animals in the forest.

Correct Answer: Nine times

Solution : The correct answer is Nine times.

Any conducting coil's ability to resist changes in current flow is known as self-inductance. A solenoid's self-inductance increases by nine times when the number of turns in the coil triples without any change in the coil's length. The coil's self-inductance is directly proportional to the square of the number of turns. The formula for the self-inductance (L) of a coil is L= μ⋅N2⋅A​/ l.

Correct Answer: The Constitution does not provide for their direct enforcement.

Solution : The correct option is The Constitution does not provide for their direct enforcement.

Fundamental duties in the Indian Constitution are not directly enforceable by law. While they are mentioned as a part of the Constitution, there are no legal provisions for their enforcement through the courts. They serve more as moral and ethical obligations for citizens.

Correct Answer: 273

Solution : Given:
11 : 133 :: 16 : ? :: 22 : 507

Square the first number and then add 1 and the first number to the resultant, to get the second number –
Like, 11 : 133→(11)² = 121; 11 + 1 = 12; 121 + 12 = 133
And, 22 : 507→(22)² = 484; 22 + 1 = 23; 484 + 23 = 507
Similarly, follow the same pattern for 16 : ?→(16)² = 256; 16 + 1 = 17; 256 + 17 = 273

So, the missing number is 273. Hence, the third option is correct.

Correct Answer: 15 years

Solution :

Given:
Adam's age = 20 years
Also, Adam's age = 4 × Mary's age
⇒ Mary's age = Adam's age ÷ 4
⇒ Mary's age = 20 ÷ 4 = 5 years.

Let us assume that after A years, Adam's age is twice the Mary's age;
Adam's age after A years = (20 + A) years, and Mary's age after A years = (5 + A) years.
Also, after A years, Adam’s age = 2 × Mary’s age
⇒ (20 + A) = 2(5 + A)
⇒ 20 + A = 10 + 2A
⇒ 20 – 10 = 2A – A
⇒ A = 10 years
Therefore, Mary's age after 10 years will be 15 years, and Adam’s age after 10 years will be 30 years.

So, Mary's age after 10 years will be 15 years. Hence, the second option is correct.

Correct Answer: 12

Solution : Given:
2 × 16 = 8, 8 × 8 = 1, 6 × 12 = 2

Like, 2 × 16 = 8→16 ÷ 2 = 8
8 × 8 = 1→8 ÷ 8 = 1
6 × 12 = 2→12 ÷ 6 = 2
Similarly, for 12 × 144 = ?→144 ÷ 12 = 12

Hence, the second option is correct.

Correct Answer: 20%

Solution : As per the chart,
The sum of all the central angles in a pie chart is 360°.
The corresponding angle for children using a scooter = 72°
The required percentage = $\frac{72^\circ}{360^\circ}$ × 100 = 20%
Hence, the correct answer is 20%.

Correct Answer: 7.2 km

Solution : According to the instructions given, the diagram is as follows –

Here, A is the starting point and F is the finishing point and AF is the total distance from the starting point.

AB = 2 km; BC = 6 km; CD = BE = 2km; DF = 12 km; DE = EF = 6 km
And, AE = AB + BE = 2 + 2 = 4 km

By applying the Pythagoras theorem –
(AF)² = (AE)² + (EF)²
(AF)² = (4)² + (6)² = 16 + 36 = 52
⇒ AF = √52 = 7.2 km

So, the total distance from the starting point is 7.2 km. Hence, the third option is correct.

Correct Answer: Knowledge processors

Solution : The correct answer is Knowledge processors.

Fifth-generation computers, often known as knowledge processors, were envisioned as powerful computing systems capable of not just processing data and doing computations but also understanding and working with human knowledge more intelligently and naturally. These systems would excel at activities such as natural language comprehension, expert reasoning, and knowledge-based problem-solving.
