If all the external angles of n sided convex polygon are in AP ..... 

 I have understood this question in the solution but one DOUBT 

when we factorize we dont consider the other values and thus end up in 18 but why not the other side ???? At what point does that become concave polygon??

Please help guys !!!!!!

(a)   The sixth century is known as the most turbulent and unsettling period in human history - the Roman Empire began to fall, civilizations in Persia, Indonesis and South America collapsed and major religions experienced considerable change as natural events were viewed as omens.
(b)   Many of the social transformations resulted from widespread crop failures and the explosion of plague around the globe, which in turn were caused by major climatic changes.
(c)   Beginning in about the year 535, according to historical and archaelogical records, the weather was colder and drier, sunlight diminished, snow fell in summer and regions of persistent drought suffered floods.
(d)   The beginning of the Dark Ages may have been a result of a massive volcanic eruption in the 6th century, according to a volcanologist at the Department of Energy's Los Alamos National Laboratory.

How is second statement an inference? Doesnt it look more like a fact?? 

Please help :/

question 30: in a circle if two chords intersect say chord AB and CD intersect at M, then AM*MB= CM*MD................is this true for all cases? or is this true only if both the chords intersect each other at 90 degree angles?

In an examination there are x questions. If the number of students who answered y or more questions wrongly, where 1 <=y <= x, is given by 2^(x-y), and the total number of wrong answers is 8191, find x.

answer:13...

Please explain someone....:/

What is wrong with this approach:

1 mistake: {2^(x-1)} - {2^(x-2) }

2 mistakes:{2^(x-2)} - {2^(x-3) }

and so on till

x-1 mistakes: 2^1 - 2^0

x mistakes: 2^0

hence total mistakes= 2^(x-1)

Where am i going wrong ....can anyone please tell?
