Ответ:
A) selling price of computer is $1329.05
B) Profit is $265.05
C) Profit percentage = 24.9%
Step-by-step explanation:
Given as :
The cost price of computer = c.p = $1064
The marked price of computer = m.p = $1399
The marked percentage discount = d = 5%
Let The selling price of computer = s.p
Now, According to question
discount% =![\dfrac{m.p - s.p}{m.p}](/tpl/images/0441/6451/79f97.png)
Or, d% =![\dfrac{m.p - s.p}{m.p}](/tpl/images/0441/6451/79f97.png)
Or, 5% =![\dfrac{1399 - s.p}{1399}](/tpl/images/0441/6451/758f0.png)
Or,
= 1 - ![\dfrac{s.p}{1399}](/tpl/images/0441/6451/6bf1b.png)
Or,
= 1 - ![\dfrac{5}{100}](/tpl/images/0441/6451/96266.png)
Or,
= ![\dfrac{95}{100}](/tpl/images/0441/6451/97658.png)
∴ s.p =
× 1399
Or, s.p = $1329.05
So,The selling price of computer = s.p = $1329.05
Now, Profit = selling price - cost price
or, p = s.p - c.p
Or, p = $1329.05 - $1064
∴ Profit = $265.05
Now, Profit % =![\dfrac{\textrm profit}{c.p}](/tpl/images/0441/6451/6841d.png)
Or, p% =![\dfrac{\textrm 265.05}{1064}](/tpl/images/0441/6451/2b226.png)
∴ p% = 0.249
i.e p = 0.249 × 100
So, profit percentage = 24.9%
Hence, A) selling price of computer is $1329.05
B) Profit is $265.05
C) Profit percentage = 24.9% Answer
