Explanation

The chapter shows in Example 3 that total cost = (number of items) × (price per item) for each type, then add them together. Jowar roti costs ₹30 each, so x plates cost 30x. Pulao costs ₹20 each, so y plates cost 20y. Total = 30x + 20y.

Solution Steps

  1. Step 1: Cost of x plates of Jowar roti = 30 × x = 30x

  2. Step 2: Cost of y plates of Pulao = 20 × y = 20y

  3. Step 3: Total amount = 30x + 20y
