25w, a refrigerator for Rs. 40w, and a washing machine for Rs. 35w. The average price of these items is Rs. 90,000. What is the price difference (in Rs.) between the refrigerator and the microwave?Solution
ATQ;
Total cost = average × number of products = 90000 × 3 = 270000
Hence, 25w + 40w + 35w = 100w = 270000 ⇒ w = 2700
Difference = (40w − 25w) = 15w = 40500
