Question
An article is sold at a loss of 10% and its selling price
is Rs. 210 less than the selling price when it is sold at a profit of 20%. If the article is actually sold at a profit of Rs. 150, then find its selling price.Solution
ATQ,
Let the cost price of the article = Rs. 100x
According to the question,
100x × 1.20 - 100x × 0.90 = 210
⇒ 120x - 90x = 210
⇒ x = 210 ÷ 30 = 7
So, cost price of the article = 100 × 7 = Rs. 700
Actual selling price = 700 + 150 = Rs. 850
