marked price of the mobile is 8800. what will be the cost price (in) of the mobile?​

Answer 1

Given:

Discount = 25%

Profit = 10%

Marked Price = 8800

To Find :

Cost Price of a mobile

Solution:

Finding Discount:

Discount = 25% of Marked Price

Discount = 25%x8800

Discount = 2200

Finding Selling Price:

Selling Price = Marked Price - Discount

Selling Price = 8800 - 2200

Selling Price = 6600

Finding Cost Price:

$= > CP = \dfrac{100}{100 + Profit\%} \times SP$

$= > CP = \dfrac{100}{100 + 10} \times 6600$

$= > CP = \dfrac{100}{110} \times 6600$

$= > CP = \dfrac{660000}{110}$

$= > CP = 6000$

Hence, the Cost Price of mobile is Rs 6000
