Question

The cost of notebook is $\mathrm{Rs}.18\frac{3}{4}$. How many notebook can be purchased for $\mathrm{Rs}.1012\frac{1}{2}$ ?

Answer 1

Given : The cost of notebook is$Rs.18\frac{3}{4}$ $=\mathrm{Rs}.\frac{75}{4}$

Suppose we can buy $x$ no. of books from the given total amount

Total Cost of $x$ number of notebook $=$ $\mathrm{Rs}.1012\frac{1}{2}$ $=\mathrm{Rs}.\frac{2025}{2}$

Number of books purchased $=\frac{\text{Total cost of notebook}}{\text{Cost of one notebook}}$

$=\frac{2025}{2}÷\frac{75}{4}$

$$\begin{gathered} =\frac{2025}{2}\times \frac{4}{75} \\ =27\times 2 \\ =54 \end{gathered}$$

Hence, the number of notebook purchased is $54$
