Correct Answer: Yardang

Solution : The correct option is Yardang.

Yardangs are geological formations generated in dry or desert locations by the deflating effect of wind. They are the consequence of abrasive wind-blown particles selectively eroding soft or easily erodible sedimentary material. When prevailing winds erode weaker areas of the terrain repeatedly, they form elongated, parallel ridges and troughs, with the ridges formed of more resistant material. Yardangs, which are significant structures in desert landscapes of varied sizes and shapes, are often orientated in the direction of prevailing winds and provide unique insights into the erosional processes forming arid settings.
 

Correct Answer: 16

Solution : The sum of the interior angle Polygon A = 1260°
If the sides of the polygon A are n_A.
⇒ (n_A – 2) × 180° = 1260°
⇒ (n_A – 2) = $\frac{1260°}{180°}$ = 7
⇒ n_A = (7 + 2) = 9
Each interior angle of a regular polygon B = $\frac{900}{7}$
If the sides of the polygon B are n_B.
⇒ 180° × (n_B – 2) = $\frac{900}{7}$ × n_B
⇒ 180n_B – $\frac{900}{7}$ × n_B = 360
⇒ $\frac{360}{7}$ × n_B = 360
$\therefore$ n_B = 7
The sum of sides of polygons A and B = 7 + 9 = 16
Hence, the correct answer is 16.

Correct Answer: QOMK

Solution : Given:
BDFH : YWUS :: JLNP : ?

Like, BDFH : YWUS→(BY, DW, FU, HS) are opposite pairs.
Similarly, for JLNP : (?)→(JQ, LO, NM, PK) are opposite pairs.

Thus, JLNP is coded as QOMK. Hence, the first option is correct.

Correct Answer:

Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of the question figure with all the option figures, the given question figure is embedded only in the second option figure.

Hence, the second option is correct.

Correct Answer: Sumesh requested Raman to lend him some money as he needed it urgently.

Solution : The correct choice is the first option.

The steps for conversion are as follows:

• The pronoun "me" (first person) is changed to "him" (third person).
• The reporting verb "said" is changed to "requested" in the imperative sentence.
• The infinitive form i.e. "to + base form of the verb" is used in the case of the imperative sentence.

Therefore, the sentence in the reported speech is: "Sumesh requested Raman to lend him some money as he needed it urgently."

Correct Answer: ACDB

Solution : The third option is correct.

Here, the given sentences discuss the progression and consequences of global warming. So, the logical flow of the sequence would be:

• (A) introduces the rise in the world's temperature and its effect, global warming.
• (C) explains the cause: increased carbon emissions leading to global warming.
• (D) details the effect: the rise in global temperature causing the melting of polar ice caps.
• (B) concludes by highlighting the consequence: the potential rise in sea levels impacting islands and coastal regions due to melted ice caps.

Correct Answer: 23

Solution : 5 + 2 + A + 6 + B + 7 + C = 20 + A + B + C
Possible values of (A + B + C) = 1, 4, 7, 10, 13, 16, 19, 22, 25
Again,
5 + A + B + C – 2 – 6 – 7 = 0 or Multiple of 11
⇒ 5 + A + B + C – 15 = 0 or Multiple of 11
From the above possible values, for (A + B + C) = 10 we get 0
So, A + B + C = 10
Now,
If A = 5, B = 3, C = 2
⇒ 2A + 3B + C = 10 + 9 + 2 = 21
If A = 3, B = 5, C = 2
⇒ 2A + 3B + C = 6 + 15 + 2 = 23
If A = 3, B = 2, C = 5
⇒ 2A + 3B + C = 6 + 6 + 2 = 17
If A = 2, B = 5, C = 3
⇒ 2A + 3B + C = 4 + 15 + 3 = 22
Hence, the correct answer is 23.

Correct Answer: INR 4.2 crores

Solution : Let the total expenditure be INR $100x$.
According to the question,
Interest on Loans = 17.5%
$\frac{17.5}{100} \times 100x = 24500000$
$⇒17.5x=24500000$
$⇒x=1400000$
Total expenditure = 14,00,00,000
Expenditure on advertisement = 15%
Expenditure on taxes = 10%
Expenditure on research = 5%
Total expenditure = 15 + 10 + 5 = 30%
The total amount of expenditure on advertisement, taxes, and research and development is $140000000  \times \frac{30}{100}$ = INR 4,20,00,000 = INR 4.2 crores
Hence, the correct answer is INR 4.2 crores.

Correct Answer: 143

Solution : Given:
6 × 2 × 9 = 269; 8 × 7 × 1 = 781

The third number remains at the third position while the first and second numbers swap positions.
Like, 6 × 2 × 9 = 269
And, 8 × 7 × 1 = 781
Similarly, follow the same pattern for 4 × 1 × 3 = 143

Hence, the fourth option is correct.

Correct Answer: 3 : 16

Solution : Mean proportion of 1.6 and 3.6
$=\sqrt{ab}=\sqrt{1.6\times 3.6}=2.4$
Now, the third proportion of 5 and 8
$=\frac{b^2}{a}=\frac{8^2}{5}=\frac{64}{5}$
$\therefore$ Ratio of mean proportion to third proportion = $2.4:\frac{64}{5}$ = 12 : 64 = 3 : 16
Hence, the correct answer is 3 : 16.
