Answer:
![\boxed{loss\% \: = 10\%}](https://img.qammunity.org/2021/formulas/mathematics/high-school/fp05oirz9e2cz9s8lv71blqvg7oqqcc3qp.png)
![\boxed{selling \: price = </strong><strong>Rs</strong><strong> </strong><strong> </strong><strong>450}]()
Explanation:
Given,
Cost price of 25 kg of vegetables ( CP ) = 25 × 20
= Rs 500
Loss amount = Rs 50
Selling price ( SP ) = ?
Loss percent = ?
Now, let's find the loss percent :
![\mathsf{ (loss)/(cost \: price) * 100\%}](https://img.qammunity.org/2021/formulas/mathematics/high-school/hrdwbsun5rz8nuirjtktlxxi2y2670lc1d.png)
![\mathsf{ = (50)/(500) * 100\%}](https://img.qammunity.org/2021/formulas/mathematics/high-school/8slehuz2q3n57iw5sbfsudmzsk9dyvvjst.png)
![\mathsf{ = 10\%}](https://img.qammunity.org/2021/formulas/mathematics/high-school/xssmgeo4k9zbre7k9lksmuuyer3xe7hneb.png)
Loss % = 10 %
Now, let's find the selling price:
![\mathsf{ (CP(100 - l\%))/(100) }](https://img.qammunity.org/2021/formulas/mathematics/high-school/8tjbw9b1rv9hyu7hp5lospfsoezkrnqf2r.png)
![\mathsf{ = (500(100 - 10))/(100)}](https://img.qammunity.org/2021/formulas/mathematics/high-school/s51s3vltgo869qj8mkqhhip94gx1mp2ch3.png)
![\mathsf{ = (500 * 90)/(100) }](https://img.qammunity.org/2021/formulas/mathematics/high-school/1afvqspj2a9s3fhd58zj9c9wbljywx00hj.png)
![\mathsf{ = (45000)/(100) }](https://img.qammunity.org/2021/formulas/mathematics/high-school/7rnjb7gss8zmfzz1q6kp2d75rzwehq9lmw.png)
![\mathsf{= 450}](https://img.qammunity.org/2021/formulas/mathematics/high-school/yrozhzdop9b2oeva099qr2gv273cqr89l6.png)
