The value of $\frac{(0.1×0.1 × 0.1 +0.02 × 0.02 × 0.02)}{(0.2×0.2×0.2+0.04 × 0.04 × 0.04)}$ is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 0.125
$\frac{(0.1×0.1 × 0.1 +0.02 × 0.02 × 0.02)}{(0.2×0.2×0.2+0.04 × 0.04 × 0.04)}$
⇒\(\frac{0.1^3 + 0.02^3}{0.2^3 + 0.04^3}\)
⇒\(\frac{0.1^3 + 0.02^3}{2^3(0.1^3 + 0.02^3)}\)
⇒\(\frac{1}{8}\) = 0.125 Answer
