What is the result of (0.53 + 0.13 - 0.63) ÷ (3 × 0.5 × 0.1 × 0.6)?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. -1.

If a + b + c = 0, then a3 + b3 + c3 = 3abc

Here, 0.5 + 0.1 + (-0.6) = 3 × 0.5 × 0.1 × (-0.6) = -(3 × 0.5 × 0.1 × 0.6)

(0.53 + 0.13 - 0.63) ÷ (3 × 0.5 × 0.1 × 0.6)

=−(3×0.5×0.1×0.6)(3×0.5×0.1×0.6)=\frac{-(3 × 0.5 × 0.1 × 0.6)}{(3 × 0.5 × 0.1 × 0.6)}

= - 1
