A) \[9\frac{2}{11}\]
B) \[9\frac{1}{11}\]
C) \[2\frac{9}{11}\]
D) \[4\frac{11}{12}\]
Correct Answer: B
Solution :
\[\because \] x is 10%more than y. \[\therefore \,\]\[\,x=\frac{110}{100}y=\frac{11}{10}y\] \[\therefore \] Percentage less\[=\frac{x-y}{x}\times 100%\] \[=\frac{\left( \frac{11}{10}-1 \right)y}{\frac{11}{10}y}\times 100%\] \[=\frac{100}{11}%=9\frac{1}{11}%\]
