\( \Large \frac{\left[0.5 \times 0.5 \times 0.5 + 0.2 \times 0.2 \times 0.2 + 0.3 \times 0.3 \times 0.3 - 3 \times 0.5 \times 0.3 \times 0.2 \right]}{\left[ 0.5 \times 0.5 + 0.2 \times 0.2 + 0.3 \times 0.3 -0.5 \times 0.2 - 0.2 \times 0.3 - 0.5 \times 0.3 \right]} = ? \)

A) 1
B) 0.6

C) 0.4
D) 0.03

Correct answer:
A) 1

Description for Correct answer:

Given expression

\( \Large \frac{a^{3} + b^{3} + c^{3} - 3abc}{a^{2} + b^{2} + c^{2} - ab - bc - ca} \)

= a + b + c

= 0.5 + 0.2 + 0.3

where, a = 0.5, b = 0.2, c = 0.3
= 0.5 + 0.2 + 0.3 = 1
