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)
$$\eqalign{ & a = 2.361 \cr & b = 3.263 \cr & c = 5.624 \cr & a + b - c = 0 \cr & 2.361 + 3.263 - 5.624 = 0 \cr & 0 = 0 \cr & \therefore {a^3} + {b^3} - {c^3} + 3abc \cr & \Rightarrow 0 \cr} $$This Question Belongs to Arithmetic Ability >> Algebra
