Question

If the cost of a book is Rs 25.75, find the cost of 24 such books.

Answer 1

Cost of one book = Rs. 25.75

∴ Cost of 24 books = Rs. 25.75 $\times$ 24
= $\frac{2575}{100}\times 24$
= $$\begin{gathered} \frac{103}{4}\times 24=103\times 6 \\ =618 \end{gathered}$$

Hence, the cost of 24 books is Rs. 618.
