Study the given table and answer the question that follows.
The table shows the marked prices (in ₹) and percentages of discount offered for five different products.

If product Q is sold at 53% profit and product S is sold at 80% profit, then what will be the sum of the cost prices of Q and S?

₹1,000

Selling price of Q = \(\frac{100 }{85}\) × 900

= \(\frac{17 }{20}\) × 900

= 765

Q is sold at 53% profit . So ,

153% of cost price = 765

Cost price =  \(\frac{765 }{153}\) × 100

= 500

Selling price of S = \(\frac{75 }{100}\) × 1200

= \(\frac{3 }{4}\) × 1200

= 900

S is sold at 80% profit . So ,

180% of cost price = 900

Cost price =  \(\frac{900 }{180}\) × 100

= 500

So , Sum of cost price of Q and S = 500 + 500 = 1000
