Answer 1

Given:

A vendor bought five buttons for a rupees

To find:

Solution:

From given, we have,

A vendor bought five buttons for a rupees  

The cost price of 5 buttons = Rs. 1

gain 25%.​

The selling price of 5 buttons =$\dfrac{100+25}{100} \times1 = \dfrac{125}{100}=\dfrac{5}{4}$  = Rs. 5/4

Therefore, we have,

For the selling price of Rs. 5/4, buttons sold = 5

For the selling price of Rs. 1, buttons sold = 5 × 4/5 = 4

Therefore, a vendor should sell 4 buttons for 1 rupee to gain 25%.​
