Quant by Arun Sharma

[abhijit111]

The sole purpose of this Thread is to bring together the CAT aspirants who are solving the Quant book by Arun Sharma. This will be a common place to discuss any doubts while solving the questions. As there are many questions in the book where either the Hint/Solution is missing or the answer itself is wrong. It will be very nice of you all to help people clear their doubts and also they could learn various methods of problem solving. This thread is not for advertising and should be taken in the right spirit.

hi abhijeet nd all,

its a gud thing to bring Arun sharma to r disscussion plate as most of us go thru it.....nd smewhr or the other finds some prob.....in solveing that..........

what i want to add is as for now we should just restrict our scope to LOD 1 and LOD 2 questions or AS,as LOD 3 are too much nd hardly question of such type r asked newhr.................

Just Another PAGAL

Hi,
Could you plz post the question. And one more thing, it would be better if we could discuss one chapter at a time.What say ???

[abhijit111]

hey!
I have got the question.. . It goes like this

Solve the following inequalities
13. x^2-7x+12 < |x-4|

a. x<2 b. x>4 c. 2<x<4 d.2<=x<=4


the answer is 'c' 2<x<4. If you substitute the values given in the option you can easily make out that only option 'c' satisfies the given inequality. there are many questions in quant where you can directly substitute the values and get the result... Cheers!!!1

Hi.. Here's another approach.. Instead of directly substituting which will be time consuming, we can play around with the equations to save some time

x^2-7x+12 < |x-4|
=(x-3)*(x-4)<|x-4|
Makes it simple now..
If we substitute the same we get the answer

Good initiative.
Arun Sharma is a book with very good questions but very bad explanations.
This thread will help us explore the solutions in a better way.

Alos, LOD3 for profit and loss sucks, the problems are simply long with nothing much interesting.
So, it can be skipped ( i wasted one whole day on it grrrrr )
