The value of b is 520.
Step-by-step explanation:
Here, b represents the price of the laptop,
Since, discount percentage = 5 %,
So, the discount = 5% of b =![\frac{5b}{100}](/tpl/images/0758/3056/918ec.png)
Thus, the price of laptop after discount = Original price of laptop - Discount
According to the question,
