#### Solution

Suppose, the lady started with x rupees.
Money spent on shopping $= \frac{x}{2}\text{ rupees }$
Remaining amount$= x - \frac{x}{2} = \frac{x}{2} \text{ rupees }$
After giving a rupee she had $= (\frac{x}{2} - 1) \text{ rupees }$
Money spent on lunch$= \frac{1}{2}(\frac{x}{2} - 1) \text{ rupees }$
After giving a two - rupee tip she had $= \frac{1}{2}(\frac{x}{2} - 1) - 2 = \frac{x - 2 - 8}{4} = \frac{x - 10}{4} \text{ rupees }$
Money spent on a book $= \frac{1}{2}(\frac{x - 10}{4}) \text{ rupees }$
After spending three rupees on bus fare she had $= \frac{1}{2}(\frac{x - 10}{4}) - 3 = \frac{x - 10 - 24}{8} = \frac{x - 34}{8} \text{ rupees }$
Now,
$\frac{x - 34}{8} = 1$
or x - 34 = 8
or x = 42
Therefore, she started with 42 rupees .
