Answer :

Let's analyze the situation step-by-step to determine who read less: Rashmi or Pari.

1. Total Number of Pages:
The book contains a total of 100 pages.

2. Pages Read by Rashmi:
Rashmi read a specific number of pages, which is given to be 25 pages.

3. Pages Read by Pari:
Pari read a fraction of the book. Specifically, she read [tex]\(\frac{2}{5}\)[/tex] of the book.

4. Calculating Pages Pari Read:
To find out how many pages Pari read, we need to compute [tex]\(\frac{2}{5}\)[/tex] of 100 pages:
[tex]\[ \text{Pages Pari read} = \frac{2}{5} \times 100 = 40 \, \text{pages} \][/tex]

5. Comparing Pages Read:
Now we have the following information:
- Rashmi read 25 pages.
- Pari read 40 pages.

To determine who read less, we compare the two quantities:
[tex]\[ 25 \, \text{pages} \quad \text{vs} \quad 40 \, \text{pages} \][/tex]

6. Conclusion:
Since 25 is less than 40, Rashmi read fewer pages compared to Pari.

Thus, the final answer is that Rashmi read less.
