A product is sold for $240 after a 20% discount. What was the original price?

Here are the solutions to the questions: Q1) A product is sold for 240 after a 20% discount. What was the original price? Step 1: Determine the percentage of the original price represented by the discounted price. A 20% discount means the selling price is 100\% - 20\% = 80\% of the original price. Step 2: Set up an equation to find the original price. Let P be the original price. 0.80 × P = \240 Step 3: Solve for P. P = (\240)/(0.80) P = \300 The original price was \300. Q2) If 5 pens cost 12.50, what is the cost of 8 pens? Step 1: Calculate the cost of one pen. Cost per pen = (\12.50)/(5 pens) Cost per pen = \2.50 per pen Step 2: Calculate the cost of 8 pens. Cost of 8 pens = \2.50/pen × 8 pens Cost of 8 pens = \20.00 The cost of 8 pens is \20. Q3) A train travels at 90 km/h. How far will it go in 2 hours and 30 minutes? Step 1: Convert the total time to hours. 30 minutes = (30)/(60) hours = 0.5 hours Total time = 2 hours + 0.5 hours = 2.5 hours Step 2: Use the formula Distance = Speed × Time. Distance = 90 km/h × 2.5 h Distance = 225 km The train will go 225 km. Q4) A man spends 3/5 of his salary. If he earns 2,500 monthly, how much does he save? Step 1: Determine the fraction of salary saved. If he spends (3)/(5) of his salary, he saves the remaining fraction. Fraction saved = 1 - (3)/(5) Fraction saved = (5)/(5) - (3)/(5) Fraction saved = (2)/(5) Step 2: Calculate the amount saved. Amount saved = (2)/(5) × \2,500 Amount saved = (2 × \2,500)/(5) Amount saved = (\5,000)/(5) Amount saved = \1,000 He saves \1,000$.
