CAT2011 : 80(no prep); CAT2013: 93.54(QA :97+ ; VA: 78) No war is lost until you know it!

@aimsuccess2011 you know that sum of the length of the two sides of a triangle has to be more than the third side of the same triangle. Additionally it has been mentioned that there are only natural numbers as the length of the side. So a + b + c = 10 and a+b>c. Punch the numbers and get the answer. Hope this helps.

ABCD is a square of a side is 10 units.There are four point p,q,r,s inside the square that triangle ABP,BCQ,CDR and DAS(triangle) are equilateral triangle .Find the area in(Sq unit) of a quadrilateral PQRS?

option (3) 27

In such cases draw the diagram and then split it into right angle triangles and rectangles

There are 6 points on a circle. Each point can be identified without relating it to any other points. Five events occur at 5 of these points,one after the other and each one at a different point. In how many ways can they occur such that no two successive events occur at adjacent points?

a)84

b)108

c)144

d)14

ans is 84 ! plz explain hw ?

You could create a quadratic and solve, but simpler to just do trial and error. Either you make 5, 20, 5 or 10, 10, 10 as the 3 sides since 5x20 or 10x10 gives 100.
