A shopkeeper bought three items: a smartphone for Rs.
14x, a camera for Rs. 10x, and a laptop for Rs. 16x. The average price of these items is Rs. 60,000. What is the price difference (in Rs.) between the smartphone and the laptop?Solution
ATQ; Total cost = average × number of products = 60000 × 3 = 180000
Hence 14x + 10x + 16x = 40x = 180000 ⇒ x = 4500
Difference = (16x − 14x) = 2x = 9000
