@shattereddream ok but the issue is I want to start with the basics..im week with these two topics but will start with some basic questions in that case and tag you 😃
hello everybody. i'm varatharaj doing pre final year in mechanical engineering in coimbatore(tamilnadu).Right from the day i know about cat i started dreaming being an IIM er! MBA is my passion. im preparing for CAT 2013. As i was from a lower middle class background i cant afford to pay the coaching class fee. now iam preparing for CAT using the books from my college library.
but those books are really confusing and deviated from the actual CAT questions.i dont have a pc too. so i cant refer any online materials. i spend 4 hours daily for preparing CAT. my friend advised me that 4 hours of such preparations=1 hour of preparation by using standard materials like TIME,IMS. i went to TIME and ask them whether i can get the materials alone for a cheaper price. they said they will provide material only along with a course. and that course costs 20000! i was heart broken! i desperately need some standard books. i would be greatly thankful if someone is will to donate extra materials or old materials! PG is my only hope. so please help me! thank you all

@varathawins Go for Career Launcher......they take something around 4-5 K for the materials as well as the Mock test,Test Gym.Go to their site and see the rates.....you also need to give some mock test to develop your competence level.
All those guys having Arun Sharma Quant book 5th edition, I have doubts in geometry. Kindly solve these questions and pls tag me with the answers:
1. Page no=384 , Q.no=142. Page no=385 , Q.no=22
3. Page no=385 , Q.no=24
I have just started to prepare for CAT 2013.I heard that topics to be studied in quants are:
* Geometry, (Lines, angles, Triangles, Spheres, Rectangles, Cube, Cone etc)
* Ratios and Proportion, Percentages, In-equations
* Quadratic and linear equations
* Algebra
* Profit & Loss
* Averages, Percentages, Partnership
* Time-Speed-Distance, Work and time
* Number system: HCF, LCM, Geometric Progression, Arithmetic progression, Arithmetic mean, Geometric mean , Harmonic mean, Median, Mode, Number Base System, BODMAS
* Mensuration, Allegation & Mixtures, Work, Pipes and Cisterns
* Simple Interest & Compound Interest
* Set Theory, Venn Diagram
* Installment Payments, Partnership, Clocks
* Probability, Permutations & Combinations
kindly correct me if i need to add or remove any topics.
if some one knows the detailed topicas to cover in quants. please let me know.

Thanks for the solution everyone!
some body clear my doubt :(
if 653xy is divisible by 80 then the value of x+y is:
(A) 2
(B) 3
(c) 4
(D) 6
its given as ans (d)6.but wen i solve i get 2.
@j.gayu said:some body clear my doubtif 653xy is divisible by 80 then the value of x+y is:(A) 2(B) 3(c) 4(D) 6its given as ans (d)6.but wen i solve i get 2.
80= 10*8
hence y has to be 0
now for div by 8 :=> 53x must be div by 8
its possible if x=6
hence x+y= 6+0=6 ans
hence y has to be 0
now for div by 8 :=> 53x must be div by 8
its possible if x=6
hence x+y= 6+0=6 ans
@viewpt u are getting 2 because => u are taking to be 2, and y to be 0. You very well know that for divisibility by 8 last digits have to be checked, BUT 😁 here u forgot that 80 is divisible by 16 SO last 4 digits have to be checked .Consequently, only x = 6 fits the bill. Hope it helps :)

bhai jaan hum ne bhi toh 6 hi likha hai upar..zara sa usey nihaar lo , pleeeeeeeeeeeeease
@viewpt Sorry boss galti ho gayi, yeh reply question puchne vaale k liye tha aapke liye nahi. :)
Gustakhi maaf ho sarkaar
Gustakhi maaf ho sarkaar
@j.gayu said:@viewpt :y?did u take it as 53x,the last three digits are 3xy ryt?
div by 2 says last digit should be even
for div by 4 last two digits should be div by 4
for 8 ..last 3 digits must be div by 8 and so on..
for div by 4 last two digits should be div by 4
for 8 ..last 3 digits must be div by 8 and so on..
how many terms are identical in the two APs 1,3,5....120 terms and 3,6,9...uopt 80 terms?
a)38 b)39 c)40 d)41 e)42
i know itz an easy problem but i dont get it.plz tell me the approach
a number 15 is divided into 3 parts which are in AP and the sum of their squares is 83.find the smallest no
a)5 b)3 c)6 d)8 e)7
@rk90 said:a number 15 is divided into 3 parts which are in AP and the sum of their squares is 83.find the smallest noa)5 b)3 c)6 d)8 e)7a-d, a, a+d
3a=15
a=5
Check for 3,5,7
9+25+49 = 83
a-d, a, a+d
3a=15
a=5
3a=15
a=5
3^2+5^2+7^2=83.
9+25+49 = 83
9+25+49 = 83
Smallest No. 3
@shivam_01
Absolutely . Agreed . Until and unless y is a multiple of 3 the entire term i.e 3^10*x-y can not be divisible by 3 . Like 6-1, 6-2 , 6-4 , 6-5 are not divisible by 3 but 6-3 is divisible by 3 .
What is the percentage change when 20/40 becomes 22/50 ???
