Doubt

But we can also see here, if we go anticlock-wise direction, we will meet the rest excluding G. So, i chosed "more than one of the above" since the question didnt specifically said that anticlockwise or clockwise

Question:

For what value of n, are both the roots of the equation $$x^2+nx+2=0$$ distinct and less than 2?

A

$$(-3, -2\sqrt{2}) \bigcup (2\sqrt{2}, \infty)$$

B

$$(-4, -2\sqrt{2})\bigcup (2\sqrt{2}, \infty)$$

C

$$(-2\sqrt{2}, 2\sqrt{2})$$

D

$$(2\sqrt{2}, \infty)$$

Doubt

Hi, I think we should check 3 conditions
f(2)>0
b^2-4ac>0
-b/2a<2 (the global minima must be less than 2, as if we take only the 1st and 2nd equation, we may get the values where both roots are greater than 2 right?)

Question:

Which of the following would be an appropriate title for the passage?

A

In Defense of Tolstoy’s criticism of Shakespeare

B

Shakespeare: A Philosophical Fraud

C

Overly Dramatic English Press

D

The Tenets of Shakespearan Philosophy

Doubt

Just like how in Q.3 where anti-semitism was substantiating the argument and moral prejudice was not mentioned specifically anywhere, calling it a fraud does not literally mean that Shakespere was a fraud, it is a way of saying. Putting a title using Tolstoy which was just used as an example is not what was taught in the lectures. The passage is about Shakespere not just about Tolstoy's criticism. If Tolstoy is being used then Napoleon should have also been there, Voltaire was also a critic of him, he can also be put in the title as well.

C

the proposed reforms are both feasible and sufficient to address global inequality and ecological harm.

Ecological degradation is more directly tied to wealth inequality than to industrial practices or technological innovation.

The solution seems incorrect. This was one of the more difficult questions i have encountered until now. Can you please give a detailed answer detailing why each of the options are false?

Question:

If the truck passes exactly twice through only two towns then what is the minimum amount of time (in minutes) that the truck will take to complete the MDC cycle?


Correct Answer: 210

Doubt

Hello, I have a doubt in the forth question mentioned in the video, it says what is the maximum time travelled

Sir's path starts from A to C and takes about 270 min.

However, why are we not considering the path AB+BC+CF+DF+DE+EG+GE+ED+DF+DC+CB+BA- this takes about 380 which would be the maximum and satisfy the condition of visiting all towns only twice. Kindly refer to the last question in the video solution for this question
