Correct Answer: Neither conclusion I nor II follows

Solution : The possible Venn diagram according to the given statements is as follows –

Let's analyse the conclusions –
Conclusion I: Some flashes are streaks – From the above diagram, it can be seen that there is no direct relation between flashes and streaks. Therefore, this conclusion is false.
Conclusion II: No flash is a line – From the Venn diagram, it can be seen that the circle of flash and line intersect and have some common area between them and it implies that some flash are lines. Therefore, this conclusion is false.

Therefore, neither conclusion I nor II follows. Hence, the fourth option is correct.

Correct Answer: Pride

Solution : The correct choice is the third option.

In this context, pride refers to a social group of lions. This term is specific to lions and reflects their social structure.

The meanings of the other options are as follows:

• Herd: This term is typically used for animals like cows or sheep.
• Pack: This term is often used for animals like wolves.
• Colony: This term refers to a group of animals, especially birds or insects, living together.

Correct Answer: Ragnar Frisch

Solution : The correct option is Ragnar Frisch

Norwegian economist Ragnar Frisch initially used the terms microeconomics and macroeconomics in 1933. Macroeconomics looks at the economy as a whole. To characterise his research, which used statistical methods to examine economic systems, he coined the term econometrics.

Correct Answer: 356

Solution : Given:
64 + 7 = 460 and 25 + 8 = 212

Like, 64 + 7 = 460→(64 × 7) + 12 = 448 + 12 = 460
And, 25 + 8 = 212→(25 × 8) + 12 = 200 + 12 = 212
Similarly, for 43 + 8 = ?→(43 × 8) + 12 = 344 + 12 = 356

Hence, the fourth option is correct.

Correct Answer: 40

Solution : Given: Three years ago, Raman’s salary was INR 45,000.
According to the question,
45000 × (100 + 10)% × (100 + A)% × (100 + 20)% = 83160
⇒ 45000 × $\frac{11}{10}$ × (100 + A)% × $\frac{6}{5}$ = 83160
⇒ (100 + A)% = $\frac{7}{5}$
⇒ 5(100 + A) = 7 × 100
⇒ 500 + 5A = 700
⇒ 5A = 700 – 500
⇒ 5A = 200
⇒ A = 40
Hence, the correct answer is 40.

Correct Answer: $\frac{5}{3}$

Solution : Given: The value of the trigonometric equation is $\sec \theta+\tan \theta=3$.
We know that if $\sec \theta+\tan \theta=x$. Then, $\sec \theta–\tan \theta=\frac{1}{x}$.
$\sec \theta+\tan \theta=3$   (equation 1)
⇒ $\sec \theta–\tan \theta=\frac{1}{3}$    (equation 2)
Adding equation 1 and equation 2,
$\sec \theta+\tan \theta+\sec \theta–\tan \theta=3+\frac{1}{3}$
⇒ $2\sec \theta=\frac{3\times 3 +1}{3}$
⇒ $2\sec \theta=\frac{10}{3}$
⇒ $\sec \theta=\frac{5}{3}$
Hence, the correct answer is $\frac{5}{3}$.

Correct Answer: The Deccan Plateau

Solution : The correct answer is The Deccan Plateau.

Cotton grows well in black soil which is found in Deccan plateau in India. Cotton is a xerophyte and it grows well in high temperatures i.e. from 21-30 degrees celsius. It requires long frost free climate.

Correct Answer: Westerlies

Solution : The correct option is Westerlies.

The opposite of the trade winds, which blow from east to west, are the "westerlies." Westerlies are prevailing winds that blow from west to east in the middle latitudes, typically between 30 and 60 degrees latitude in both the Northern and Southern Hemispheres. They are usually referred to as "anti-trade winds," as they do blow in the opposite direction.

Correct Answer: refused to yield

Solution : The correct choice is the third option.

The idiom, put his foot down is a figurative expression that means to assert oneself firmly, especially in making a decision or taking a stance. In the context of the sentence, the speaker begged for reconsideration, but the use of the idiom suggests that the other person firmly refused to yield or change their decision.

Correct Answer: (81, 15, 87)

Solution : Given:
(44, 63, 98); (59, 99, 149)

In the given sets, the sum of the first and second numbers equals the sum of the third number and 9. 
(44, 63, 98)→44 + 63 = 107; 98 + 9 = 107
(59, 99, 149)→59 + 99 = 158; 149 + 9 = 158
Let's check the options –
First option: (81, 15, 87)→81 + 15 = 96; 87 + 9 = 96
Second option: (54, 73, 121)→54 + 73 = 127; 121 + 9 = 130 ≠ 127
Third option: (19, 32, 44)→19 + 32 = 51; 44 + 9 = 53 ≠ 51
Fourth option: (82, 13, 96)→82 + 13 = 95; 96 + 9 = 105 ≠ 95

So, only the first option, follows the pattern of the given sets. Hence, the first option is correct.
