Answer :


:\implies\bf\:m+n=18\:\longrightarrow\:(I)


:\implies\sf\:2mn=-24\:\longrightarrow\:(II)


:\implies\bf\:mn=-12\:\longrightarrow\:(III)

Answer - A :


:\implies\tt\:(5)/(3m)+(5)/(3n)


:\implies\tt\:(15(m+n))/(9(mn))


:\implies\tt\:(15(18))/(9(-12))


:\implies\tt\:-(15)/(6)


:\implies\:\boxed{\bf{\purple{-(5)/(2)}}}

Answer - B :


:\implies\tt\:(4)/(m^2)+(4)/(n^2)


:\implies\tt\:(4(m^2+n^2))/((mn)^2)


:\implies\tt\:(4(m^2+2mn+n^2-2mn))/((mn)^2)


:\implies\tt\:(4[(m+n)^2-2mn])/((mn)^2)


:\implies\tt\:(4[(18)^2-(-24)])/((-12)^2)


:\implies\tt\:(4(324+24))/(144)


:\implies\tt\:(348)/(36)


:\implies\:\boxed{\bf{\orange{(29)/(3)}}}
