This is a simple Work and Rate problem.

Robin reads 16 pages in 1 hour so he takes \(\frac{1}{16}\) hours to read 1 page.

Rohan reads 25 pages in 1 hour so he takes \(\frac{1}{25}\) hours to read 1 page and \(\frac{2}{25}\) hours to read 2 pages.

Comparing the times taken by Robin\(\frac{1}{16}\) and Rohan \(\frac{1}{12.5}\)

Since the denominator in Robin's time is greater than that of Rohan's time. \(\frac{1}{16}<\frac{1}{12.5}\)

Rohan will take greater number of hours to read two pages.
