A shopkeeper marks the price of an article in such a way that after allowing a discount of 22%, he gets a gain of 11%. If the marked price is Rs.888, then the cost price of the article is:

₹ 624

Marked price of the article = Rs. 888

SP of the article = 888 × $\frac{78}{100}$ =  692.64

∴ CP of the article = 692.64 × $\frac{100}{111}$ = 624
