may be at the begining im not sure.. we were posting questions for xat i guess..
@albiesriram said:We cant simply find the 100th term of a fibonacci series... it should be mentioned unless it is undoable by the conventional formula..
How to solve if we have 100th term ?
Suppose a1, a2, a3 ... an are the terms of the fibonacci series numbers.
sum of their squares is
a1^2+ ( an.an+1 ) - a1a2
sum of them will be
an+2 - a2

How you got that .. Is this a predefined property or something ?

yup fundamentals of fibonacci series..

Oh okey .. I will check that out!

Find the SP of goods if 2 salesmen claim to make 25% profit each, one calculating at CP and one at sp, the difference in profits earned being rs 100 and sp being the same in both case.
if Four squares of size 1*1 are chosen at random on a chess board of size 8*8,what is the probability that they are in the same diagonal?

Sp/4-y/4=100
SP-y=400
SP-x=0.25SP
x=0.75SP
SP-y=0.25y
Sp=1.25y
y/4=400
y=1600
SP=5/4 *1600=2000?

2*8c4/64c4 = 140/635376=35/158844?

2000?

2*8C4 +4(7C4+6C4+5C4+4C4) = 364 in the numerator?
Diagonal on a chessboard is not only the longest diagonal (not the geometry waala definition) on a square...it is any path on which a bishop moves na...so 2 diagonals of length 8 hai, but next to them 4 of length 7, and 4 of length 6, 5, 4, 3, etc....

@vbhvgupta Taking S.P as 100 we get C.P as 80 and 75. So difference in profits in 5. So for diff in Profit to be 100, S.P shud be 2000. Is it correct????
