sold it at a loss of 10%. With this money, she again purchased a new laptop and sold that at a profit of 25%. Find the profit earned by her in the whole transaction.Solution
ATQ, Money obtained by Pooja through first sale = (100 - 10)% of 80,000 = (0.9) x 80,000 = Rs. 72,000 Money obtained by Pooja through second sale = (100 + 25)% of 72,000 = (1.25) x 72,000 = Rs. 90,000 Net profit earned by Pooja = 90,000 - 80,000 = Rs. 10,000
