MCQs will be uploaded in the Advanced Learning System from today onwards. Initially, Maths MCQs will be uploaded which will be mostly of simple type with, "Real Stuff" in between and subsequently.
If the sum of the coefficients in the expansion of $(x+y)^n$ is 4096, then the greatest coefficient in the expansion is _ _ _ _ . Solution $C_0 + C_1 + C_2 + C_3 + ......................... + C_n =4096 $ $\therefore 2^n = 4096 =2^{12} $ $\Rightarrow n = 12 $ Greatest coefficient = ${}^{12}{C_6} = 924$
