25^(@)C

The coefficient of x^(24) in ((25C_(1))/(25C_(0))-x)(x-2^(2)(25C_(2))/(25C_(1))(x-3^(2)(25C_(3))/(25C_(2)))(x-4^(2)(25C_(4))/(25C_(3)))......,(x-25^(2)(25C_(25))/(25C_(24))) is equal to 2925

If 25C_0 25C_2 +2. 25C_1 25C_3 +3. 25C_2 .25C_4+....+ 24. 25C_23.25C_25=k. 49C_lambda+50C_mu , then the value of 2k-lambda-mu is greater than (where mu,lambda lt 25 )

if 25C_(n+5)=25C_(2n-1) then sum of all values of n is:

If ^25C_r= ^25C_(2r+1) ,the value of ^rC_5 is
