Question : Comprehension: Read the given passage and answer the questions that follow. The Black Drongo also known as the King Crow, is a small Asian bird of the drongo family. Previously, it was seen as a subspecies of the African Fork-tailed Drongo but is now recognised as a full species. It is a common resident breeder in much of tropical southern Asia from southwest Iran through India and Sri Lanka to southern China and Indonesia. It is a wholly black bird with a distinctive forked tail and measures 28 cm in length. Feeding on insects, it is commonly found in open agricultural areas and light forest areas throughout its range, perching conspicuously on a bare perch or along power or telephone lines. The species is famous for its aggressive behaviour towards much larger birds, such as crows, and never hesitates to dive-bomb any birds of prey that invade its territory. Smaller birds often nest in the well-guarded vicinity of a nesting Black Drongo. The Black Drongo has been introduced to some Pacific islands, where it has thrived and become abundant to the point of threatening and causing the extinction of native and endemic bird species there. Drongos fly with strong flaps of the wing and are capable of fast manoeuvres that enable them to capture flying insects. With short legs, they sit upright on thorny bushes, bare perches or electricity wires. They may also perch on grazing animals. The Black Drongo is found predominantly in open country and usually perches and hunts close to the ground. They are mostly aerial predators of insects but also glean from the ground or off vegetation. They are found as summer visitors to northeastern Afghanistan and northern Pakistan but are mainly resident south from the Indus Valley up to Bangladesh and into India and Sri Lanka. Question: What was the impact of trying to introduce the species to the Pacific islands?
Option 1: They decreased in numbers drastically.
Option 2: They returned to the lands of their origin.
Option 3: They proved to be a threat to the local birds.
Option 4: They did not survive in the changed climate conditions.
Correct Answer: They proved to be a threat to the local birds.
Solution : The third option is the correct choice.
The impact of introducing the Black Drongo species to some Pacific islands was that they thrived and became abundant to the point of threatening and causing the extinction of

Question : If $a, b, c$ are all non-zero and $a+b+c=0$, then find the value of $\frac{a^2}{b c}+\frac{b^2}{c a}+\frac{c^2}{ab}$.
Option 1: $3$
Option 2: $4$
Option 3: $1$
Option 4: $\frac{1}{2}$
Correct Answer: $3$
Solution : Given: $a+b+c=0$ According to the question, $a^3+b^3+c^3=3abc$ Dividing both sides by $abc$, we get $\frac{a^3}{abc}+\frac{b^3}{abc}+\frac{c^3}{abc}=\frac{3abc}{abc}$ ⇒ $\frac{a^2}{bc}+\frac{b^2}{ac}+\frac{c^2}{ab}=3$ Hence, the correct answer is 3.
Question : If $\cos A=\frac{15}{17}, 0 \leq A \leq 90^{\circ}$, then the value of $\cot(90° - A)$ is:
Option 1: $\frac{8}{15}$
Option 2: $\frac{2 \sqrt{2}}{15}$
Option 3: $\frac{\sqrt{2}}{15}$
Option 4: $\frac{7}{15}$
Correct Answer: $\frac{8}{15}$
Solution : Given: $\cos A=\frac{15}{17}$ $\sec A=\frac{1}{\cos A}=\frac{17}{15}$ $\cot(90^\circ - A)=\tan A=\sqrt{\sec^2 A-1}$ $=\sqrt{(\frac{17}{15}^2)-1}$ $=\sqrt{\frac{289}{225}-1}$ $=\sqrt{\frac{289-225}{225}}$ $=\sqrt{\frac{64}{225}}$ $=\frac{8}{15}$ Hence, the correct answer is $\frac{8}{15}$.

Question : Directions: Study the bar diagram and answer the question. Total number of boys and girls in five different departments of a college.
The percentage of the boys from the Biology department compared to the total number of boys from all the departments together is:
Option 1: $33\frac{1}{2}\%$
Option 2: $50\%$
Option 3: $33\frac{1}{3}\%$
Option 4: $30\%$
Correct Answer: $33\frac{1}{3}\%$
Solution : From the given graph, The total number of boys from all the departments = 60 + 220 + 100 + 160 + 120 = 660 The number of boys in the Biology Department = 220 The required percentage = $\frac{\text{The number of boys in the
Question : Directions: In a certain code language, EDITOR is coded as CBGQLO. What is the code for FOLDER in that code language?
Option 1: DMJABO
Option 2: BMJBCR
Option 3: DMJACO
Option 4: DMJABR
Correct Answer: DMJABO
Solution : Given: EDITOR is coded as CBGQLO.
Subtract 2 from the place value of the first three letters and subtract 3 from the place value of the last three letters of EDITOR to obtain the required code – E – 2 = C; D – 2
