Change the following statements using expressions into statements in ordinary language. (For example, Given Salim scores r runs in a cricket match, Nalin scores (r + 15) runs. In ordinary language - Nalin scores 15 runs more than Salim.)
A notebook costs Rs. p. A book costs Rs. 3p.

Answer

To convert the given mathematical expressions into ordinary language, we will follow these steps:

### Step 1: Identify the Costs
- The cost of a notebook is given as Rs. p.
- The cost of a book is given as Rs. 3p.

### Step 2: Understand the Relationship
- The cost of the book (3p) is related to the cost of the notebook (p). Specifically, the book costs three times as much as the notebook.

### Step 3: Formulate the Ordinary Language Statement
- We can express this relationship in ordinary language as follows:
- "The cost of a book is three times the cost of a notebook."

### Final Statement
- Therefore, the ordinary language statement is: "A book costs three times as much as a notebook."
