C The question asks us to identify a flaw in the argument? What is the flaw according to you? Option 3 is the obvious flaw in the question. Does a small student population guarantee a low faculty/student ratio? No, it does not. What if the number of faculty is absurdly low in the school? In that case, the ratio would still be pretty high. So in order to have a low ration, we need a small student population and a large faculty presence. Only in this case is a low student/faculty ratio guaranteed.

E This is a simple question. The question stem simply says that anyone who is an Indian politician is corrupt and the only exception is Indira Gandhi.

A We can analyze the options as follows: Option A: we cannot arrive at a definite relationship between Ram’s and Lalita’s commission. Option B: if Sita earns more than Lalita, then Ram definitively does so. Option C: If Sita earns more than Lakshman, then Ram definitely earns more than Lalita and Lakshman both. Option D: If Sita and Lakshman earn the same amount of commission, then Ram definitely earns more than Lalita. Option E: If Ram and Lakshman earn the same amount of commission, then Ram again definitely earns more than Lalita as Lakshman earns more than Lalita.

B This is a very simple and straightforward question: what resulted in the drop in customers? An increase in rates. How to reverse the situation: reverse the rates.

B How do we weaken this argument? By simply proving that the three companies has some other reason for their growth. If that is proved, then we are sure that MAD AD House is not responsible for their good fortune, and hence, we can safely say they are the not best advertising solution in the market.

C This is more a mathematical question than a critical reasoning question. We know the price of a car is India is 120 less than the price of purchasing a car in Pakistan. Even after adding transportation and tariff charges, it is cheaper to buy a car in India. How is this possible? Only one way: if the duties, charges etc. are less than the difference in prices, so that difference is not covered and prices in India remain cheaper. We find this in option C.'Instead of being concerned with what actually happens in practice ... [economics] is increasingly preoccupied with developing pseudo-mathematical formulas. These provide models of behaviour which ever quite fit what actually happens, in a way which resembles the physical sciences gone wrong: instead of equations describing reality, economics produces equations describing ideal conditions and theoretical clarity of a type which never occurs in practice'.

A The two answer choices which baffle in this question are options A and D. Option A is a strongly worded option which asserts that economists should not rely on mathematics at all. On the other hand, option D mentions something that is clearly not mentioned directly in the paragraph. This leads us to believe that option D might be the answer but a closer evaluation clarifies the situation. Option D does nothing else but rephrase the last two lines of the paragraph, talking about a truer description of human nature. On the other hand, if option A was correct, then in that case there would be formulae, complex or real.

B The clear answer to this is option B. We need to weaken the argument given in the passage. The author talks about how economists are struggling with painting the real picture in this world by over-relying on complex mathematical formulations (which are theoretical in nature). Which statement runs counter to this? Option B clearly negates this statement and provides the exact opposite.

B The main assertion made by author of the passage is how geography comes in the way of spreading religions. This makes option 2 the easy to identify answer for this question.
