and sold it at a loss of 15%. With this money, he again purchased a new smartphone and sold that at a profit of 20%. Find the profit earned by him in the whole transaction.Solution
ATQ, Money obtained by Amit through first sale = (100 - 15)% of 25,000 = (0.85) x 25,000 = Rs. 21,250 Money obtained by Amit through second sale = (100 + 20)% of 21,250 = (1.2) x 21,250 = Rs. 25,500 Net profit earned by Amit = 25,500 - 25,000 = Rs. 500
