Answer:

Correct Answer: D

Solution:

Given, the CP of an item be Rs. x and SP of an item be Rs. y. Here, Y = 1.2 x If the CP of an item is 15% less = 85% of X = 0.85 X According to the question, $ 0.85X\times \frac{130}{100}=1.2x-76 $ $ 11.05X=12X-760 $
$ \Rightarrow $ $ 12X-11.05X=760 $

$ \Rightarrow $ $ 0.95X=760 $

$ \Rightarrow $ $ X=\frac{760}{0.95} $

$ \Rightarrow $ $ X=800 $ So, CP of an item is Rs. 800.
