Main koi bada log nahi hu.. bade log to Estallar12 hai .. fisherking hai.. hanushanand hai.. anupam001 hai.. roadkill hai .. wiper hai ..uff.. bahut saare bade log hai.. !
time walon ka best MC kaun hai? CAT level??

cat level yo pata nahi VA easy hai kyunki but 1304 1307 1310 attempt kar sakte ho
Engg 😁 😁 we can do anything
omg wats goin on here , this waz supposed to be a MBA related forum ... but here its goin on da ouuu la la ouuu la la way !!
sometimes u need a break

Logarithms:
1. log(a) + log(b) = log(ab)
2. log(a) - log(b) = log(a/b)
3. b^(log a) = a^(log b)
4. log (base - a^q) [N^p] = p/q * log(base - a) N
5. a^(log(base-a) [X]) = X (contributed by @Vascent )
6. Characteristic of a logarithm: The integer part of the logarithm, after converting the remaining non-integral part to a non-negative quantity
7. Mantissa of a logarithm: The part after that decimal point. It is always positive
8. log(x) has two types of graph, one increasing and the other decreasing. It depends on the base (a) of the logarithm. If a>1, increasing. If a
9. In case of log(base-a)[N] , N>0 , a >0, a not equal to 1.
Ratio/Proportion/Variation:
a,b,c,d are in proportion:
1. If b^2 = a*c => b is the mean proportional of a and c
2. a/b = b/c => c is the third proportional of a and b
3. a/b = c/d => d is the fourth proportional of a,b,c
If (a/b) > 1 -> for x>0, (a+x) / (b+x)
If (a/b) for x>0, (a+x) / (b+x) > (a/b) --> Useful in DI
Types of variations:
1. Directly proportional: A = k*B , k is a constant
2. Inversely proportional: A = k/B
3. Joint variation: A = k* B/ C , A = k1*B + k2*C
That's it I guess, individual questions are rare in this, generally they are clubbed with other topics..

take x=1 (x>0)
(3+1)/(2+1) = 4/3 which is >1
These forms were always confusing and I never learnt them that way :S .
@YouMadFellow
Making a very small addition :)
One very very useful formula in Logarithm---
a^(log(base-a) [X]) = X

Sorry a typo, I wanted to write,

@anupam001 Bhai of the following aimcats which are closest to Cat only QA wise (No point in asking for VA..time sucks at VA)- 1304,1303,1302 and 1301.
My Cat is on 16th so i'll be attempting only one or maybe two..

try 1304 it is the closest...1303 is ok in terms of quant. You can leave 1301 and 1302.

thanks anupam001..
Time and Distance, Work:
1. Average speed = Total distance/ Total time :|
2. Relative speed-> opposite direction = v1 + v2, same direction = |v1-v2|
3. Circular motion (speeds a,b , track length L, starting at the same point):
a) If ratio of speeds is m:n, they meet at (m+n) distinct points, if opposite direction, and they meet at |m-n| distinct points, if same direction. (The points are distributed symmetrically)
b) First meeting time = L/(a+b) or L/(|a-b|) respectively
c) The sum of the distances travelled by the two, between any two meeting points, when travelling in opposite direction is L
d) The difference of the distances travelled by the two, between any two meeting points, when travelling in same direction is L
e) Clocks concept can be clubbed with this: Hour hand moves at (1/2) degree per minute, Minute hand moves at 6 degree/minute. We can use relative speed concept to find out angle between them etc. Detailed Clocks in another post.
4. Linear motion (speeds a,b , track length L, starting at opposite ends):
If ratio of the speeds is not more than 1.5,
a) they meet at m distinct points where m>n and m:n is the ratio of the speeds, but the sequence of the points repeats after every (m+n) meetings.
b) the sum of the distances travelled between each meeting point = 2*L
If ratio > 1.5, brute force method is the only method I think.
5. Man Days/ Man hours concepts:
For a particular work to be done, the man days required to complete the work is the same or varies in direct proportional to the work to be done
Ex: 5 mandays = 5 men 1 day OR 1 man 5 days
So, in general N*D*H/W = constant,where N = number of men, D = number of days, H = hours worked per day, and W is the work to be done. W is generally taken as 1, or any other suitable quantity.
Money is shared between the workers in the proportion of their work done during the time period.
Thanks to All SB guys for all the concepts above ! 😃
