Let the no that attended the meeting b n. nC2=nP2/2!=49875078 n(n-1)/2=49875078 n^2-n=99750156 n^2-n-99750156=0 using QUADRATIC FORMULAR n=(-b+/-root(b^2-4ac))/2a n= 9988 OR -9987(discard since humans aint negative) hence,n=9988 again let the no of people that attended d meeting b x when the handshake is 23041866 xC2=xP2/2!=x(x-1)/2=23041866 x^2-x=46083732 x^2-x-46083732=0 using QUADRATIC FORMULAR X=6789 OR -6788(Discard) x=6789 therefore the no that would have missed to reduce the handshake is n-x=9988-6789=3199 ans 3199 1 Like |

Solution: This is a simple case related to sum of an A.P. The equation is (49,875,078=n(n-1)/2)-(23,041,866=n(n-1)/2) Solving each seperately and collecting like-terms, the answer obtained is 3,199.......one can alternately solve it using the full formula for sum of an A.P(s=n/2(2a+d(n-1)) for each of the values and add '1' to each of the answers before subtracting(the addition of '1' being a pre-requisite to represent the no of people) |

smurfy: I got it up to n^2 - n - 99750156 = 0. I couldn't factorise it.Yeah me too but this is how I arrived at the solution: n^2 - n - 99750156 = 0 n(n-1) = 99750156 The above equation is simply a product of two numbers with difference of one. Hence if you take the square root of both sides then round up and down, you'll will get the two numbers if the solution are whole numbers. E.g 8 * 7 = 56 Sqrt of 56 is approximately equal to 7.48 Round this up and down to get 7 and 8 which is the answer The same way sqrt of 99750156 = 9987.5 Round up and down to get 9987 & 9988 In this case, n is the bigger of the two, hence n = 9988 1 Like |
