Answer 2

The required ratio is 45:56.

Step-by-step explanation:

Consider the provided information.

Let the cost price of the book is x.

That means the selling price should be:

Selling price = x + 12% of x

Selling price = $\frac{112x}{100}$

Let marked price is represented by y.

After giving a discount of 10% shopkeeper get 112 rupees.

y - y of 10% = $\frac{112x}{100}$

$y - (y \times \frac{10}{100}) =\frac{112x}{100}\\0.9y=1.12x\\y=\frac{1.12x}{0.9}$

The ratio of cost price and marked price is:

$\dfrac{x}{\frac{1.12x}{0.9}} =\dfrac{0.9}{1.12}=\dfrac{45}{56}$

Hence, the required ratio is 45:56.
