Correct Answer: (2)

Solution: (2)

Case I

C.P. of article $=$ Rs. $x$

$\therefore$ S.P. of article $=\frac{120 x}{100}$ $=$ Rs. $\frac{6 x}{5}$

Case II,

C.P. $=\frac{110 x}{100}=$ Rs. $\frac{11 x}{10}$

Profit $=\frac{6 x}{5}-\frac{11 x}{10}$ $=\frac{12 x-11 x}{10}=$ Rs. $\frac{x}{10}$

$\therefore$ Required per cent $=\left(\frac{\frac{x}{10}}{\frac{6 x}{5}}\right) \times 100$ $=\left(\frac{x}{10} \times \frac{5}{6 x}\right) \times 100$ $=\frac{100}{12}=\frac{25}{3} \%$
