### A shopkeeper sells four products namely P, Q, R and S at different prices. The cost price of one unit of a product P is Rs. 90 less than the cost price of one unit of a product Q. The shopkeeper sells one unit of a product Q at Rs 310 and earns 175/6% profit. The average cost price of one unit of each of the four products is Rs 402.5. The shopkeeper gives a discount on product S which is equal to 10% of its selling price and still makes a profit of Rs. 100 on sale of one unit. The cost price of one unit of product R is Rs 520.
