Question

The marked price of a cordless phone is rupees 1200. If it is sold at a discount of 25 %, find its selling price

Answer 1

$\sf\large\underline{Given:}$

• $\tt{The\:marked\: price\:of\: phone=Rs.1200}$
• $\tt{Sold\:at\:a\: discount=25\%}$

$\sf\large\underline{To\: Find:}$

• $\rm{The\: selling\: price\:of\: phone=?}$

$\sf\large\underline{Solution:}$

• By applying formula to calculate SP]

$\sf\large\underline{Formula\:used:}$

$\rm{\implies SP=MP\times\bigg(\dfrac{100-D\%}{100}\bigg)}$

$\rm{\implies SP=1200\times\bigg(\dfrac{100-25}{100}\bigg)}$

$\rm{\implies SP=1200\times\bigg(\dfrac{75}{100}\bigg)}$

$\rm{\implies SP=12\times\:75}$

$\rm{\implies SP=Rs.900}$

$\sf\large{Hence,}$

$\rm{\implies Selling\: price\:_{cordless\: phone}=Rs.900}$

$\sf\large\underline{Some\: related\: formula}$

$\rm{\implies SP=MP-P}$

$\rm{\implies D\%=\dfrac{MP-SP}{MP}\times\:100}$

Answer 2

Given

Mp=1200

D=25%

to find:

Selling price

Sp=Mp(100-d/100)

Sp=1200×(100-25/100)

Sp=1200×75/100

Sp=12×75=900

Therefore, selling price of phone is rs900
