Question

Raju reads $\frac{2}{3}$ rd of a book. He finds that still there are 100 pages to be read. The total number of pages in the book are?

Answer 1

If Raju reads $\frac{2}{3}$ rd of a book. He will still have
$\frac{1}{3}$rd of the book to complete.
Let the total number of pages of the book be y
Then $\frac{1}{3}y=100$
Hence y = 3 $\times$ 100
= 300
