Option 1: DBCA
Option 2: DCBA
Option 3: DBAC
Option 4: DCAB
Correct Answer: DCAB
Solution : The correct choice is the fourth option: DCAB.
The paragraph starts with sentence D, which serves as an introduction, providing essential information about what an onion is and why it is grown. It is then followed by sentence C, which provides additional
Question : A frustum of a right circular cone, whose height is 18 cm, large base radius is 25 cm, and small base radius is 20 cm, is melted to form a small sphere of diameter 2 cm. How many spheres will be formed?
Option 1: 6287
Option 2: 6862
Option 3: 4575
Option 4: 5857
Correct Answer: 6862
Solution : Here, the height of the frustum ($h$) = 18 cm Large base radius ($R$) = 25 cm Small base radius ($r$) = 20 cm So, the volume of the frustum = $\frac{\pi h}{3}(R^2+Rr+r^2)$ = $\frac{\pi×18}{3}(25^2+25×20+20^2)$ = $9150\pi\ \text{cm}^3$ Now, radius of the sphere = $\frac{2}{2}$
Question : Comprehension: Wildlife and nature have largely been associated with humans for numerous emotional and social reasons. A simple stroll around the park amidst some birds provides a fresh breath of life and charges our batteries. Apart from a bird feeder in the backyard, we can also take up other active pastimes, such as hiking, hunting, canoeing, or wildlife photography, to relieve our parched nerves. Since prehistoric times, animals have been highly useful to us in providing food, clothing, and a source of income. Studies indicate that woodpeckers are capable of destroying 90% of codling moth larvae residing under the bark of trees. This shows the significance of wildlife and wildlife habitat for preserving genetic diversity. Hence, places, where agriculture, forests, and fisheries depend on crops or stocks, can ensure that such living resources are enough to withstand the ever-increasing list of threats. Further, in medicine, the development of new drugs and treatments is largely dependent on wildlife and wildlife habitat. Interestingly, most pharmaceutical products are a result of discovering or developing wildlife species, not discoveries made through traditional chemistry principles. Today, most medicinal remedies contain at least one ingredient derived from a wild plant or animal. Biodiversity is the variety of living beings within an ecosystem or on our planet. It is a measurement of the health of ecosystems. Biodiversity also plays a part in the function of climate. In terrestrial habitats, tropical areas are rich in species, whereas polar areas support fewer species. The conservation of biodiversity is inevitable for the survival of humans. Based on the passage above, choose the correct option for the following questions:
Question: According to the passage, which of the following statements is true?
Option 1: Most medicinal remedies contain at least one ingredient derived from a wild plant or animal.
Option 2: Wildlife habitat plays no role in preserving genetic diversity
Option 3: Since prehistoric times, animals have been not been useful to us
Option 4: Biodiversity is a measurement on the cultural ecosystems
Correct Answer: Most medicinal remedies contain at least one ingredient derived from a wild plant or animal.
Solution : The correct choice is the first option.
The passage mentions that the development of new drugs and treatments in medicine is largely dependent on wildlife and wildlife habitat. It specifically

Question : Parts of the following sentence have been given as options. Select the option that contains an error.
The poor undergoes / several problems in life / that could be / solved with money.
Option 1: that could be
Option 2: several problems in life
Option 3: the poor undergoes
Option 4: solved with money
Correct Answer: the poor undergoes
Solution : The correct option will be the third option.
The subject, "The poor" is plural, as it represents the class of poor people, so the plural form of the verb i.e., "undergo" should also be used.
Therefore, the correct sentence is: The poor undergo
Question : Before the battle, the ratio of tanks to planes in an army was 5 : 3. During the war, 1000 tanks were destroyed and 800 planes were destroyed. The ratio of tanks to planes became 2 : 1, what was the number of tanks after the war?
Option 1: 2000
Option 2: 1000
Option 3: 3000
Option 4: 4000
Correct Answer: 2000
Solution : Given: Before the battle, the ratio of tanks to planes in an army was 5 : 3. Let the number of tanks before battle = $5x$ and the number of planes before battle = $3x$. During the war, 1000 tanks and 800 planes were destroyed.
Question : Directions: Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
Option 1: 4 – 27
Option 2: 6 – 125
Option 3: 5 – 63
Option 4: 7 – 216
Correct Answer: 5 – 63
Solution : Let's check the options –
First option: 4 – 27; 4 – 1 = 3 and 33 = 27 Second option: 6 – 125; 6 – 1 = 5 and 53 = 125 Third option: 5 – 63; 5 – 1
Question : The pair of compounds used as anaesthetic in medicines :
Option 1: Ether, Ammonia
Option 2: Nitrous oxide, Chloroform
Option 3: Chloroform, Nitrogen dioxide
Option 4: Nitrogen dioxide, Ether
Correct Answer: Nitrous oxide, Chloroform
Solution : The correct option is Nitrous oxide, Chloroform.
One of the first anesthetics was nitrous oxide. It is a gas that has no color or smell. It is not appropriate for severe surgical anesthesia, while it can cause a mild sedative and analgesic condition.
Question : If $r\sin\theta=\frac{7}{2}$ and $r\cos\theta=\frac{7\sqrt3}{2}$, then the value of $\theta$ is:
Option 1: 30°
Option 2: 45°
Option 3: 60°
Option 4: 75°
Correct Answer: 30°
Solution : Given: $r\sin\theta=\frac{7}{2}$ and $r\cos\theta=\frac{7\sqrt3}{2}$ So, $\frac{r\sin\theta}{r\cos\theta}=\frac{\frac{7}{2}}{\frac{7\sqrt3}{2}}$ $⇒\tan\theta=\frac{1}{\sqrt{3}}=\tan 30°$ $\therefore\theta = 30°$ Hence, the correct answer is 30°.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given sets. (12, 7, 1385); (19, 15, 3484) (NOTE: Operations should be performed on the whole numbers without breaking down the numbers into their constituent digits. E.g. 13 - operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.)
Option 1: (17, 15, 1550)
Option 2: (11, 7, 955)
Option 3: (21, 16, 5165)
Option 4: (16, 14, 1321)
Correct Answer: (21, 16, 5165)
Solution : Given: (12, 7, 1385); (19, 15, 3484)
In the given sets, subtract the cubes of the second number from the first number to get the third number. (12, 7, 1385)→123 – 73 = 1728 – 343 = 1385 (19, 15, 3484)→19
