Approach please
Hi all,
Sorry from deviating from topic.
I have created a thread to compile all cat 2016 important video links. It will help you all.

Concept 1 : Circular Motions based on two or three objects moving around a circular track,In such cases the relative speed becomes effective speed of the bodies,Let us assume the three objects are moving with a speed of a, b & c on a track of length L. (a>b>c)
1) If two bodies are moving in the same direction, their relative speed is (a-b).
2) If two bodies are moving in the opposite direction, their relative speed is (a+b).
***********Number of distinct Points at which body meets on a track ________******
1) If they are moving in same direction, they will meet at (a-b) distinct points, where a and b are coprimes
2) If they are moving in opposite directions, they will meet at (a+b) distinct points, where a and b are coprimes
3) All these points will be equidistant from each other.
Note : If they aren't coprimes then cancel the common part , make them coprime (a:b) and then use the above points.

Pichla waal dui bodies k liye tha ....ab waala koun b tino bodies k liye hogaaa :beers isko bhi dekhlo bhai - bandhu 😄
Number of Distinct points 3 bodies will meet on a circular track
.●Step 1: Find out pairwise distinct meeting points.
●Step 2 : The overall answer will be the Highest Common Factor of the pairwise values
.
■Example: suppose A, B and C are running with speeds of 7, 9 and 13 on a circular track. A and B are running clockwise, whereas C is running anti-clockwise.●A and B will have 9 - 7 = 2 distinct meeting points.●A and C will have 7 + 13 = 20 distinct meeting points.●B and C will have 9 + 13 = 22 distinct meeting points.■A, B and C will have HCF (2, 20, 22) = 2 distinct meeting points.They will meet at 2 distinct points on the track

A salesman has to choose between two schemes of remuneration.The first scheme has a fixed salary of rs 3700 and a commission of 2% on sales above rs 50000. The second scheme has no salary but offer commission only. The commission starting from 3% of sales for the first rs 50000 or part there of increase at the rate of 1 percentage point for every increase of rs 50000 or part there of sales upto a maximum of 20% of sales. what is the minimum value of sales above which he can prefer the second scheme
CAT 2016 press release says registrations record 7-year high; PaGaLGuY told you this yesterday
We told you yesterday that CAT 2016 registrations had surged to 2,32,434. A press release by the CAT authorities confirm this. The press release says that registrations for the Common Admission Test (CAT) to Indian Institutes of Management and other leading B-schools have shot up to a 7-year high. There were 2,18,664 registrations for the test last year.
“From the period CAT 2010 to CAT 2016, this is the highest number of applicants,” said Professor Rajendra K. Bandi, Convenor, CAT 2016. “While we still have a majority of male candidates (67%), the percentage of female candidates has marginally increased by 1% compared to last year, which is a good sign, but not good enough,” he observed.
“However, if we look at the total increase in the applications compared to last year, which is close to 14,000, almost half of these additional applications have come from female candidates. This is a positive sign. That means, the increase of female candidates is more than the increase of male candidates,” he explained.
The number of PWD (Persons with Disability) applicants has increased from 901 to 938. “In this category, the percentage of male candidates is very high (more than 80%), which is something to think about. Our social systems need to encourage female PWD students. However, on the positive side, the percentage of female PWD candidates has increased from 14.76% to 17.48%. Small positive steps, but miles to go on this,” Prof. Bandi added.
