$$\frac{{38 \times 38 \times 38 + 34 \times 34 \times 34 + 28 \times 28 \times 28 - 38 \times 34 \times 84}}{{38 \times 38 + 34 \times 34 + 28 \times 28 - 38 \times 34 - 34 \times 28 - 38 \times 28}}$$ is equal to = ?
Answer & Solution
Correct Answer:
Option
D
$$\eqalign{
& {\text{Given experssion ,}} \cr
& \frac{{{a^3} + {b^3} + {c^3} - 3abc}}{{{a^2} + {b^2} + {c^2} - ab - bc - ca}} \cr
& \left( {Let,\,38 = a,\,34 = b,\,28 = c} \right) \cr
& = a + b + c \cr
& = 38 + 34 + 28 \cr
& = 100 \cr} $$
