Question : Comprehension: Read the given passage carefully and answer the questions that follow.
As the world's population approaches 8 billion and resource use intensifies, pollution is becoming more extensive, pervasive, and persistent. It affects our health through the food we eat, the water we drink, and the air we breathe. By 2025, the world's cities will produce 2.2 billion metric tonnes of waste every year, more than three times the amount produced in 2009. That said, pollution is not a new phenomenon and is largely controllable and often avoidable, as shown in some countries and cities that have succeeded in decoupling economic growth from pollution and waste accumulation.
With the end goal of eradicating all forms of pollution by 2030, the UN Environment Programme was tasked by the UN Environment Assembly to coordinate the implementation of a global plan reiterating that pollution is not only an environmental priority, it's a priority for the achievement of the Sustainable Development Goals.

Question : A field is in the form of a circle. The cost of fencing around it at INR 12 per metre is INR 2,640. What is the area (in m2) of the field? (Take $\pi=\frac{22}{7}$)
Option 1: 1,925 m2
Option 2: 3,850 m2
Option 3: 2,772 m2
Option 4: 5,544 m2
Correct Answer: 3,850 m2
Solution : Given: A field is in the form of a circle. Use the formulas, The perimeter of the circle = $2\pi r$, The area of the circle = $\pi r^2$, where $r$ is the radius. The cost of fencing around it at INR 12
Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? $18,6,2, ?, \frac{2}{9}$
Option 1: $\frac{1}{3}$
Option 2: $\frac{1}{9}$
Option 3: $\frac{2}{3}$
Option 4: 1
Correct Answer: $\frac{2}{3}$
Solution : Given: $18,6,2, ?, \frac{2}{9}$
Multiply the previous term by $\frac{1}{3}$ to obtain the next term. $18×\frac{1}{3}=6;6×\frac{1}{3}=2;2×\frac{1}{3}=\frac{2}{3};\frac{2}{3}×\frac{1}{3}=\frac{2}{9}$
So, $\frac{2}{3}$ is the missing term in the given series. Hence, the third option is correct.
Question : If the sum of the diagonals of a rhombus is $L$ and the perimeter is $4P$, find the area of the rhombus.
Option 1: $\frac{1}{4}\left(\mathrm{~L}^2-\mathrm{P}^2\right)$
Option 2: $\frac{1}{4}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Option 3: $\frac{1}{2}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Option 4: $\frac{1}{4}\left(\mathrm{~L}^2+3 \mathrm{P}^2\right)$
Correct Answer: $\frac{1}{4}\left(\mathrm{~L}^2-4 \mathrm{P}^2\right)$
Solution : Given: The sum of the diagonals of a rhombus is $L$. Perimeter = $4P$ ⇒ Sides = $\frac{4P}{4}$ = $P$ Now, the sum of the diagonals = $L$ Let one of the diagonal be $d_1$ and another diagonal be $d_2$. ⇒ $(\frac{d_1}{2})^2 + (\frac{d_2}{2})^2
Question : Select the most appropriate option to substitute the underlined segment in the given sentence. If there is no need to substitute it, select ‘No substitution required’.
The train was delayed in order to an accident.
Option 1: since

Option 1: 428
Option 2: 427
Option 3: 328
Option 4: 338
Correct Answer: 428
Solution : 15 = 3 × 5 20 = 2 × 2 × 5 35 = 5 × 7 LCM of 15, 20 and 35 = 7 × 5 × 3 × 2 × 2 = 420 Adding the remainder 8 to 420, we get 428, which,
