If a = 2.361, b = 3.263, and c = 5.624, then the value of a³ + b³ - c³ + 3abc is?

A. (p- q)(q - r)³ + (r - p)³

B. 3(p - q)(q - r)(r - p)

C. 0

D. 1

Answer: Option C

Solution(By Examveda Team)

$$\eqalign{ & a = 2.361 \cr & b = 3.263 \cr & c = 5.624 \cr & a + b - c = 0 \cr & 2.361 + 3.263 - 5.624 = 0 \cr & 0 = 0 \cr & \therefore {a^3} + {b^3} - {c^3} + 3abc \cr & \Rightarrow 0 \cr} $$
