• C. $196\frac{2}{3}\%$
• D. $183\frac{1}{3}\%$
• E. $194\frac{2}{3}\%$

Answer 1

The correct option is D $183\frac{1}{3}\%$

Number of books purchased for library B in 2003 = 240
Number of books purchased for library B in 2006 = 680
$\therefore$ Percentage increase,
$=\frac{680-240}{240}\times 100$
$=\frac{440}{240}\times 100$
$=\frac{550}{3}=183\frac{1}{3}\%$
