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 ?

5Comments »@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.

@raunak soudhani is there any other approach other than hit n try as we also need to satisfy a+c >b and b+c >a and perimeter given is a bigger value.
