Answer:

2.5% Profit

Step-by-step explanation:

the cost price of a box and pen is rs80.the box is sold at 10% profit and the pen is sold at 10% loss.if the sp of the box is 28rs more than that of the pen ,calculate the profit or loss percent in the whole​

Let say cost Price of Box = Rs B

Then Cost Price of Pen = Rs 80 - B

Box is sold at 10% Profit so

Box Selling Price = Box Cost Price + Profit

=> Box Selling Price = B + (10/100)B = Rs 1.1B

Pen is sold at 10 % Loss

Pen Selling Price = (80-B) - (10/100)(80-B)  = Rs 72 - 0.9B

SP of Box = 28 + SP of Pen

=> 1.1B = 28 + 72 - 0.9B

=> 2B = 100

=> B = 50

Total Selling Price = 1.1B + 72 - 0.9B = 72 + 0.2B

= 72 + 0.2*50

= 72 + 10

= 82

Total SP = Rs 82

Total CP = Rs 80

Profit = 82 - 80 = Rs 2

Profit % = (2/80)*100 = 2.5%

Answer:

2.5% profit

Step-by-step explanation:

Let the cost price of box be x

let the cost price of pen be 80-x

Now for profit of box

s.p =c.p-c.p of p%

s.p = x-x *10/100

s.p= 1.1x

Now for loss of pen

s.p = c.p-c.p of loss%

s.p = (80-x)-10/100 of (80-x)

s.p = 72-0.9x

Now

s.p of box= 28+s.p of pen

1.1x = 28+72-0.9x

20x =100

x =50

total s.p = 1.1x+72-0.9x

By putting the value of x

total s.p = 72+0.2*50

=82

s.p = 82

c.p=80

profit =s.p-c.p

=82-80

=2

Now

p% =p/c.p*100%

=2/80*100

=2.5 profit
