If \( \Large xy = x^{2}+y^{2}-xy \), then the value of \( \Large 911 \) is

A) 93
B) 103
C) 113
D) 121

Correct Answer:


B) 103

Description for Correct answer:
\( \Large x \ast y = x^{2}+y^{2}-xy \)

\( \Large 9 \ast 11 = \left(9\right)^{2}+ \left(11\right)^{2}-11 \times 9 \)

81 + 121 - 99 = 103
