each other. Find out the maximum no of team?
Read Solution (Total 4)
-
- xC2=253
X(x-1)/2*1=253
X^2-X=506
X^2-X-506=0
(X+22) (X-23)=0
X=-22,23
So Maximum no of team is 23 - 5 years agoHelpfull: Yes(1) No(1)
- xc2=253
x=23 - 4 years agoHelpfull: Yes(0) No(0)
- nc2=253
on solving we get n=23 - 4 years agoHelpfull: Yes(0) No(0)
- nc3=253
n(n-1)/2!=253
n(n-1)/2(1)=253
n(n-1)=253x2
n(n-1)=506
n^2-n-506=0
n=23 ,-22
maximum (n) is 23 - 3 years agoHelpfull: Yes(0) No(0)
