Question
A shopkeeper selling an item for Rs.(a + 500), and
suffered a loss of 20%. suppose he sells it for Rs.(2a – 500), he will make a profit of 20%. Find the value of 'a'.Solution
ATQ, CP of the item when there is loss of 20% = [(a + 500) x (5/4)] To make an 20% profit, he has to sell the article for = Rs.[(a + 500) × (5/4) × (12/10)] According to the question, [(a + 500) × (5/4) × (12/10)] = 2a – 500 Or, (a + 500) × 3/2 = (2a – 500) Or, 3a + 1500 = 4a – 1000 Or. a = 2500
