Options

B. 90
C. 105
D. 120

Answer

To find out how many pages are in the book, we can set up the problem using algebra.

Let's denote the total number of pages in the book as \( x \).

1. **Understanding the problem**: Ram reads \( \frac{1}{5} \) of the book, which means he has \( \frac{4}{5} \) of the book left to read. According to the problem, this remaining part of the book equals 60 pages.

2. **Setting up the equation**: Since \( \frac{4}{5} \) of the book is equal to 60 pages, we can write the equation:
\[ \frac{4}{5} x = 60 \]

3. **Solving for \( x \)**: To find \( x \), we can multiply both sides of the equation by \( \frac{5}{4} \):
\[ x = 60 \times \frac{5}{4} \]

4. **Calculating the right side**:
\[ x = 60 \times 1.25 = 75 \]

5. **Conclusion**: Therefore, the total number of pages in the book is \( 75 \).
