Both are questions based on same concept, the finding the coefficient concept( rather generating functions).
1)For +ve integral solutions , consider the equation
(x + x^2 + x^3.....x^11)(x + x^2 + x^3.....x^11)(x + x^2 + x^3.....x^11)...6 times = 11
Find the coefficient of x^11 in this expansion. :D
