7. Question
Osteomalacia is caused by the deficiency of:
Correct
Solution (a)
Explanation:
Osteomalacia-
- It is the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of Vitamin D.
- It is a condition in which the bones of an adult progressively soften because of inadequate mineralization of the bone. (In children the condition is called rickets.) It may occur after several pregnancies or in old age, resulting in increased susceptibility to fractures. Symptoms include bone pain, weakness, numbness of the extremities, and spasms of the hands or feet.
- Depletion of the bone minerals may be caused by lack of dietary vitamin D (or its precursor, ergosterol), inadequate exposure to sunlight (necessary for the formation of vitamin D in the body), impaired function of one of the organs involved in the absorption or metabolism of the bone minerals or vitamin D, frequent ingestion of mineral oil (in which vitamin D dissolves but is not absorbed from the intestines), or abnormalities in the bone mineralization process.

Which of the following are known as the ‘suicide bags’ of the cell?
Correct
Solution (b)
Explanation:
Lysosomes-
- They are organelle which is mostly found in animal cells; very rarely in plant cells. It is also called ‘suicidal bags’ because they are responsible for digestion.
- Each lysosome is surrounded by a membrane that maintains an acidic environment within the interior via a proton pump. Lysosomes contain a wide variety of hydrolytic enzymes (acid hydrolases) that break down macromolecules such as nucleic acids, proteins, and polysaccharides.
- These enzymes are active only in the lysosome’s acidic interior; their acid-dependent activity protects the cell from self-degradation in case of lysosomal leakage or rupture, since the pH of the cell is neutral to slightly alkaline.

A owns a house worth ₹10,000. He sells it to B at a profit of 15%. After some time, B sells it back to A at 15% loss. Find A’s loss or gain percent.
Correct
Solution (d)
A’s investment is 10,000 rupees.
He sells it at 15% profit = 10,000 * 1.15 =11500
B sells it to A at 15% loss = 11500 * 0.85 = 9,775
Hence, A’s profit = 11,500 – 9775 = 1725
Required answer = 1725/10000 = 17.25% Gain

Question 29 of 30
29. Question
Akshay sells it to Babu goods at five-thirds the rate of profit at which Babu has decided to sell it to Charan. Charan, on the other hand, sells it to Dev at one-third the rate of profit at which Babu sold it to Charan. If Dev gives ₹2145 to Charan at 10% profit, how much did Akshay buy it for?
Correct
Solution (a)
Charan’s purchase price = 2145 * 10/11 = 1950
Bharat’s rate of profit is 3 times C’s rate of profit.
Hence, Bharat sells it to Charan at 30% profit
Bharat’s price + 30% profit = 1950(Charan’s price)
Hence, Bharat’s price = 1500
Further, since Akshay’s profit rate is 5/3 times the rate of profit of Bharat,
Akshay’s profit percent would be 30 * (5/3) = 50%
Thus, Akshay’s price + 50% profit = 1500 (Bharat’s price)
Akshay’s bought it for ₹1000
Incorrect
Solution (a)
Charan’s purchase price = 2145 * 10/11 = 1950
Bharat’s rate of profit is 3 times C’s rate of profit.
Hence, Bharat sells it to Charan at 30% profit
Bharat’s price + 30% profit = 1950(Charan’s price)
Hence, Bharat’s price = 1500
Further, since Akshay’s profit rate is 5/3 times the rate of profit of Bharat,
Akshay’s profit percent would be 30 * (5/3) = 50%
Thus, Akshay’s price + 50% profit = 1500 (Bharat’s price)
Akshay’s bought it for ₹1000

Question 30 of 30
30. Question
Read the following passage and answer the questions that follow each passage. Your answer to these questions should be based on passage only.
The search for some kind of position-independent understanding of the world is central to the ethical illumination that may be sought in a non-relational approach. When Mary Wollstonecraft pilloried Edmund Burke for his support of the American Revolution without taking any interest in the status of the slaves, as if the freedom that he supported for white American people need not apply to its black slaves, Wollstonecraft was arguing for a Universalist perspective that would overcome positional prejudice and sectional favoritism. The point there is not positional comprehension, but some kind of a trans-positional understanding.
Even when a position-independent view is appropriate for an epistemological, ethical or political assessment, the reality of position dependence of observations may have to be taken into account in explaining the difficulty of achieving a positionally unbiased comprehension. The hold of positional perspectives can have an important role in making it hard for people to transcend their positionally limited visions. For example, in a society that has a long-established tradition of relegating women to a subordinate position, the cultural norm of focusing on some alleged features of women’s supposed inferiority may be so strong that it may require considerable independence of mind to interpret those features differently. If there are, for instance, very few women scientists in a society that does not encourage women to study science, the observed feature of paucity of successful women scientists may itself serve as a barrier to understanding that women may be really just as good at science, and that even with the same native talents and aptitudes to pursue the subject, women may rarely excel in science precisely because of a lack of opportunity or encouragement to undertake the appropriate education.
The observation that there are few women scientists in a particular society may not be at all mistaken, even when the conclusion that women are no good at science – when drawn from that positional observation – would be entirely erroneous. Observations from other societies where women have more opportunities could confirm that women have the ability to do just as well as men in the pursuit of science, given the necessary opportunities and facilities.
When the confines of local beliefs are strong and difficult to overcome, there can be a steadfast refusal to see that a real inequity is involved in the way women are treated in their own society, and many women are themselves led to a belief about women’s alleged intellectual inferiority based on the supposed ‘evidence of the eyes’, drawing on a faulty reading of local observations within a stratified society. In explaining the protest-free tolerance of social asymmetry and discrimination that can be seen in many traditionalist societies, the idea of positional objectivity has something of a scientific contribution to make, in giving us an insight into the genesis of an illegitimate application of positional comprehension (when the need is for a trans positional understanding).
The important notion of ‘objective illusion’, used in Marxian philosophy, can also be helpfully interpreted in terms of positional objectivity. An objective illusion, thus interpreted, is a positionally objective belief that is, in fact, mistaken in terms of trans-positional scrutiny. The concept of an objective illusion invokes both the idea of positionally objective belief, and the trans-positional diagnosis that this belief is, in fact, mistaken.
Which of the following could not take the place of the words “Universalist Perspective”?
Correct
Solution (c)
From the passage we can infer that Mary Wollencraft ridicules Edmund Burke because he supports the American Revolution but does so from the white man’s perspective. Burke is not concerned with the slaves according to Wollencraft, who states that we need to move away from positional prejudice or preconception and sectional favoritism towards trans-positional understanding.
Hence option a, b and d can take the place of Universalist Perspective. Omnipotent is all powerful and there is no mention of a powerful belief or attitude. It’s more like a superior belief or attitude.
