Answer:

Correct Answer: A

Solution:

  • Let the cost price of A be Rs. x. Then, 130% of 120% of 118% of $ x=2301 $

$ \Rightarrow $ $ \frac{130}{100}\times \frac{120}{100}\times \frac{118}{100}\times x=2301 $

$ \Rightarrow $ $ x=Rs\text{. }( \frac{2301\times 100\times 100\times 100}{130\times 120\times 118} )=Rs\text{. 1250} $
