If $$\frac{{m - 3{a^3}}}{{{b^3} + {c^3}}}$$ $$+$$ $$\frac{{m - 3{b^3}}}{{{c^3} + {a^3}}}$$ $$+$$ $$\frac{{m - 3{c^3}}}{{{a^3} + {b^3}}}$$ = 9, then the value of m is?
Answer & Solution
Correct Answer:
Option
C
$$\eqalign{
& {\text{Put }}a = b = c = 1 \cr
& {\text{Then we have }} \cr
& \frac{{m - 3}}{2}{\text{ + }}\frac{{m - 3}}{2}{\text{ + }}\frac{{m - 3}}{2} = 9{\text{ }} \cr
& m = 9 \cr} $$
Now, putting values of a, b, c in option,
Only option (C) gives value of m = 9
So, option (C) is correct.
Now, putting values of a, b, c in option,
Only option (C) gives value of m = 9
So, option (C) is correct.
