If a + b + c = 0 and a = 0.1, b = 0.2, c = -0.3, then what is (a3 + b3 + c3) ÷ (3abc)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1.
If a + b + c = 0, then a3 + b3 + c3 = 3abc
Here, a + b + c = 0.1 + 0.2 - 0.3 = 0
(a3 + b3 + c3) ÷ (3abc)
= (3abc)/(3abc)
= 1
