Thanks. I have understood till 2/3 would you pls explain the next steps. 

[Anand Iyer]

In the fraction 2/3, multiply numerator and denominator by 2, to get 4/6.  

[Adwin jha]

And why we have to multiply numerator and denominator by 2?

[Surajit Das]

To get 1 mark

[Anand Iyer]

Here's how it works.

Be aware any fraction p/q can be represented in multiple forms when the numerator and denominator are multiplied by the same value.

Thus, 2/3 = 4/6 = 6/9 = 8/12 = .(many more such equivalent fractions)

all these are equivalent.  So, if the set options had 6/9 instead of 4/6, that would have been correct.

Hope it makes sense to you now.

[Adwin jha]

Yeah now I got it. Thanks. 

[Kiran Kumar]

Let us say I should consider marks between 80 to 100 on set A. 

And marks between 60 to 79 on set B.

Suppose if I get avg mark as 79.66 for which set I should consider this marks . Generally when it is more than half I.e more than 79.50 we consider it as next whole number 80, should we do same here

This is from Wk-1 problem solving tips.

How can gcd be 'a' if we have 0 (zero) either as a numerator or as a denominator?  Please explain with some examples. 

•  gcd(0,a) = a = gcd(a,0)  

•  gcd(0,0) is undefined

It's ques no.

3.  The snipers aim according to the question it hits M first at his head/body but there is a chance that it can also hit "L" at the feet. Either way just M or both M and L it all depends on the velocity of bullet and other factors but both are possible. 

11. You can see that everyone saying and even it's mentioned in the question that round of upto two decimal places and also 3.80 = 3.8 isn't it?

Dear Sir

If 10^8 in a second, how come 10^6 would be Nearly 5000 seconds. please clarify.

Quote

As mentioned in the lecture, assume that a computer can do 10⁸ comparisons in a second. How many seconds will it take for the computer to do pairwise comparisons of one million (1, 000, 000) elements?

 Nearly 5000 seconds

Mohan

Mobile 9663368039

[Anand Iyer]

it is not 10^6.

It's 10^6 * (10^6 - 1)/2.  Recollect the formula is n(n - 1)/2

The value is very to 5 * 10^11

This is equivalent to 5000 seconds.

Pls clarify further the below.

10^11 = 5000 sec

quote:

This is equivalent to 5000 seconds.  

[Anand Iyer]

5 * 10^11 = 5 * 10^3 * 10^8 = 5000 * 10^8.

Now, 10^8 is equivalent to 1 second.

Thus, 5000 * 10^8 is equivalent to 5000 seconds.

Thanks for explaining. 

Deriving  will be,

1000000(1000000-1)/2

=1000000000000/2

=500000000000

[811_BaEco_Eve_5 Sxc]

Can anyone please help me with solution of this question

[Malabika Guha Mustafi]

@ Pallavi

Step 1. First identify which one is function of other . Here P(T) is defined, so P=y and  T =x [(Pa) is the unit of y and (k) is the unit of x].

Step 2. compute m.[ Here equation Pv= RT so c=0 , equation in y=mx form. So m=R/v=0.5] 

Step3. Put SSE formula, yi= sum ( yi- mxi)^2 .

Compute for A and B observations. You will get the result. Hope, it is clear now.

[Priyanshu Kumar]

Total time duration of mock test is 3 hrs . Almost same as qualifier exam. But I  not guess about no of questions. I have also query about this. 

Warm regards

Priyanshu

[SUHANA PARVEEN S]

@Priyanshu 

"Based on feedback about the practice tests conducted on 11 and 12 November, we have decided to increase the duration of the final Qualifier Exam to be conducted on 22 November 2020 by half an hour.

Hence, the duration of the exam will be 3.5 hours instead of 3 hours.
Exam timings will be 9am-12:30pm and 2:30pm-6pm.

There is no time cut-off for any particular subject and subjects can be attempted in any order. The entire time of 3.5 hours can be used to attempt any question of any subject."

have a look on this..3.5 hrs instead of 3 hours it is.

[Yashwardhan Banta]

Would there be partial marking for the msqs?

[Hemant Agarwal]

I see many people saying that the paper for maths and stats was difficult . The qualifier exam was for the admission in the IIT so how can you expect the paper to be easy or moderate.Beside every question which came can be done with the help of what was taught in videos . 

[Harshad Paikrao]

You are right, it was not difficult, all questions are solvable, its just the time management, if one had given around 1hr 15 mins to maths, or you start exam with maths with fresh mind, then one can get at least 60-65%.

even I made the mistake of keeping maths at the end and made silly mistakes due to less time.

Would have definitely qualified if I had started with maths, but now its diacy. 

[प्रखर Awasthi]

Please let them qualify who get less marks in just one subject,it will be great for us I am not fulfilling 40% criteria in one subject only
