Question

Paul brought and sold a computer .he wrote his business activity as followers cost price of computer =$1064 marked price of computer =$1399 discount on marked price =5%

Answer 1

A) selling price of computer is $1329.05

B) Profit is $265.05

C) Profit percentage = 24.9%

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% =
`(m.p - s.p)/(m.p)`

Or, d% =
`(m.p - s.p)/(m.p)`

Or, 5% =
`(1399 - s.p)/(1399)`

Or,
`(5)/(100)` = 1 -
`(s.p)/(1399)`

Or,
`(s.p)/(1399)` = 1 -
`(5)/(100)`

Or,
`(s.p)/(1399)` =
`(95)/(100)`

∴ s.p =
`(95)/(100)` × 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 % =
`(\textrm profit)/(c.p)`

Or, p% =
`(\textrm 265.05)/(1064)`

∴ 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

Answer 2

Profit = $265.04.

Selling price = $1329.05

Explanation:

Paul brought a Computer at a cost price of $1064.

Now ,

The marked price of the computer is given as $1399.

Also,

He is giving a total discount of 5% on the marked price of the computer i.e., $1399.

So, The selling price of computer will become 95 percent of $ 1399 which equals $1329.05.

Thus Paul sold the computer at a profit of $1329.05 - $1064

= $265.04.
