Description : Sridevi sells an article at a profit of 50%. If she had bought it at 40% less and sold it for Rs.21.50 less, She would have gained 60%. Find the cost price of the article.
Last Answer : 1st selling price=150% of x = 150x/100 = 15x/10 New Cost price=60% of x = 60x/100 = 6x/10 2nd selling price = 160% of 6x/10 = 160/100 * 6x/10 = 96x/100 Therefore 15x/10 – 96x/100 = Rs.21.50 X=Rs.39.81 Therefore cost price of the article = Rs.40 (approx.)
