Question

A shopkeeper labelled the price of his articles so as to earn a profit of 30% on the cost price. He then sold the articles by offering a discount of 10% on the labelled price. What is the actual percent profit earned in the deal?
A. 0.18
B. 0.15
C. 0.2
D. None of these

Answer 1

Le the cost price of the article be 100
to earn a profit of 30% he labelled them ₹130.
After giving a discount of 10% the selling price of the article `= 0.9 xx 130 = 117`
So, actual profit perent `= ((117 -100))/(100) xx 100 = 17%`
