Answer:

Correct Answer: B

Solution:

  • Let the CP of 1 article = Rs. x

$ \therefore $ CP of 40 articles $ =40x $ and SP of 25 articles $ =40x $

$ \therefore $ SP of 1 article $ =\frac{40x}{25} $ or $ \frac{8x}{5} $ $ Gain\text{=}SP-CP=\frac{8x}{5}-x=\frac{3x}{5} $ Gain % = $ \frac{Gain\times 100}{CP} $ $ =\frac{\frac{3x}{5}\times 100}{x}=20\times 3=60 $ %
