Correct Answer: wild

Solution : The first option is correct.

The threats mentioned in the passage, such as habitat destruction and conflicts with local people, suggest that the context is about the challenges faced by elephants in their natural, wild habitat. So, wild is the appropriate word in this context.

The meanings of the other options are as follows:

• Tame means domesticated or trained.
• Dangerous means posing a risk of harm.
• Elegant means graceful or stylish.

Correct Answer: for

Solution : The correct answer is the second option.

In this context, "for" is used as a preposition to indicate the duration or period of time during which the action or situation has been ongoing.

Therefore, the complete sentence should be: For the last ten years, we have been victims of abuse.

Correct Answer: 40, 30

Solution : Let the speed of the car starting from A be $x$ km/hr and that from B be $y$ km/hr. ($x>y$)
In opposite direction, relative speed = $(x+y)$ km/hr
In same direction, relative speed = $(x-y)$ km/hr
Distance = 70 km
⇒ $\frac{70}{x-y}$ = 7 [Use: Time = $\frac{\text{Relative Distance}}{\text{Relative Speed}}$]
⇒ $x-y$ = 10 --------------(i)
Also, $\frac{70}{x+y}$ = 1 [Use: Time = $\frac{\text{Relative Distance}}{\text{Relative Speed}}$]
⇒ $x+y$ = 70 --------------(ii)
Adding (i) and (ii),
$2x$ = 80
⇒ $x$ = 40 km/hr
Subtracting (i) from (ii),
$2y$ = 60
⇒ $y$ = 30 km/hr
Hence, the correct answer is 40, 30.

Correct Answer: eutrophication

Solution : The correct answer is eutrophication.

When nutrient levels in any water body increase, especially that of phosphate and nitrate, which leads to increases in the biomass of the water body, this process is known as eutrophication. Its initial stage is characterised by the rapid growth of phytoplankton in the upper layer of the water body. It is caused because of agricultural runoff, and industrial waste, which increase nutrient levels. It is harmful and leads to the death of the aquatic ecosystem.

Correct Answer: ÷, −, =, −, ×

Solution : Given:
(440 * 11) * 85 * 57 * (34 * 3)

Let's check the given options –
First option: +, −, =, ÷, +
⇒ (440 + 11) − 85 = 57 ÷ (34 + 3)
L.H.S. = 451 − 85 = 366
R.H.S. = 57 ÷ 37 = 1.54
L.H.S. ≠ R.H.S.
Second option: ×, =, −, ÷, +
⇒ (440 × 11) = 85 − 57 ÷ (34 + 3)
L.H.S. = (440 × 11) = 4840
R.H.S. = 85 − 57 ÷ 37 = 85 − 1.54 = 83.46
L.H.S. ≠ R.H.S.
Third option: +, ×, =, ÷, +
⇒ (440 + 11) × 85 = 57 ÷ (34 + 3)
L.H.S. = 451 × 85 = 38335
R.H.S. = 57 ÷ 37 = 1.54
L.H.S. ≠ R.H.S.
Fourth option: ÷, −, =, −, ×
⇒ (440 ÷ 11) − 85 = 57 − (34 × 3)
L.H.S. = 40 − 85 = –45
R.H.S. = ​​​57 − 102 = –45
L.H.S. = R.H.S.

So, only the fourth option satisfies the given equation. Hence, the fourth option is correct.

Correct Answer: 13 cm

Solution : Given: The height and the radius of the base of a right circular cone = 12 : 5
Let the height be $12x$ and the radius is $5x$.
Volume = 314 cm³
We know that,
Volume of a cone = $\frac{1}{3}\pi r^2 h$
⇒ $314 = \frac{1}{3} × 3.14 × 5x × 5x × 12x$
⇒ $100 = 100x^3$
⇒ $x=1$
Radius $=5x=5\times1=5$
Height $=12x=12\times1=12$
Slant height = $\sqrt{\text{height$^2$ + radius$^2$}}=\sqrt{12^2+5^2}=\sqrt{144+25}=\sqrt{169}=13\ \text{cm}$
Hence, the correct answer is 13 cm.

Correct Answer: 4

Solution : The correct choice is the fourth option.

The sentence is grammatically accurate and doesn't need any change as per the rule of conditionals. The sentence conveys the idea that Sumithra didn't miss the cab because she had hurried.

Therefore, the given sentence requires no improvement.

Correct Answer: $8$

Solution : Given: Distance = 14 km
Let the speed of the boat be $x$ km/hr.
According to the question,
$\frac{14}{(x + 2)} + \frac{14}{(x - 2)} = 3\frac{44}{60}$
⇒ $\frac{14(x - 2 + x + 2)}{(x^2 - 4)} = 3 + \frac{44}{60}$
⇒ $\frac{28x}{(x^2 - 4)}= \frac{56}{15}$
⇒ $15x = 2x^2 - 8$
⇒ $2x^2 - 15x - 8 = 0$
⇒ $2x^2 - 16x + x - 8 = 0$
⇒ $2x(x - 8) + 1 (x - 8) = 0$
⇒ $(2x + 1) (x - 8) = 0$
⇒ $x - 8 = 0$ [Since speed can not be negative]
⇒ $x = 8$ km/hr
Hence, the correct answer is 8.

Correct Answer: 10%

Solution : Expenditure on interest + miscellaneous = 20 + 24 = 44
Expenditure on tax + salary = 25 + 15 = 40
Difference = 44 – 40 = 4
Required percentage = $\frac{4}{40}×100$ = 10%
Hence, the correct answer is 10%.
