Question

# If the sum of the coefficients in the expansion of (a+b)n is 4096, then the greatest coefficient in the expansion is .15947929242924

Solution

## The correct option is C 924Sum of coefficients in the expansion of (a+b)n is equal to 2n We have 2n=4096=212⇒n=12; So, middle term is t7 t7=t6+1= 12C6=12!6!6!=924.
