If {L} and {M} are respectively the coefficient of x^{-7} in (a x+\frac{b}{x^{2}})^{11} and the coefficient of x^{7} in (b x^{2}+\frac{a}{x})^{11} then {L}+ {M}=

Correct Answer is : 1a[ coefficient of x6in(ax2+bx)12]

\frac{1}{b}[ coefficient of x^{-6} in(a x+\frac{b}{x^{2}})^{12}]

\frac{1}{a}[ coefficient of x^{6} in(a x^{2}+\frac{b}{x})^{12}]

a[ \coefficient \of \x^{-10} in(a x+\frac{b}{x^{2}})^{11}]

b[ coefficient of x^{4} in(a x^{2}+\frac{b}{x})^{11}]
