Discount is always calculated on cost price . => It means house is sold at 90% of cost price i.e, 90% of cost price is 45000. => CP x 90/100 = 45000 => CP = (45000 x 100)/90 => CP = 50000. Verify... =>Selling price = cost price - discount => 45000 = 50000 - (10% of 50000) => 45000 = 50000 - 5000 => 45000 = 45000
