Answer:

Correct Answer: A

Solution:

  • Let the CP for $ A=Rs\text{. }x $ Cost price (CP) for $ B=\frac{100+10}{100}\times x=\frac{110}{100}\times x $ Cost price (CP) for $ C=\frac{120}{100}\times \frac{110}{100}x $ Since, C pays Rs. 1848 for the article

$ \therefore $ $ \frac{120}{100}\times \frac{110}{100}\times x=1848 $

$ \Rightarrow $ $ x=\frac{1848\times 100\times 100}{120\times 110} $
$ \Rightarrow $ $ x=Rs\text{. 1400} $
