(a) ₹310.37
(b) ₹348.74
(c) ₹335
(d) ₹350

Solution:

Given, the selling price of an article is ₹329

The dealer lost 6 %

We have to find the cost price of the article.

Loss = CP - SP

Loss = CP - 329

Loss% = Loss/CP × 100

6 = (CP - 329)/CP × 100

6 = [CP/CP - 329/CP] × 100

6 = 1 - 329/CP × 100

6/100 - 1 = -329/CP

(6 - 100)/100 = -329/CP

-94/100 = -329/CP

CP = -329/-94 × 100

= 329/94 × 100

= 3.5 × 100

= 350

Therefore, the cost price is ₹350.
