3. A trader mixes 2 kg of butter which costs
$8 per kg with 3 kg of butter which costs $6 per kg.
He sells the mixture at $2.55 per 250 g. Express his
profit as a percentage of his selling price.​

Answer 1

Answer:

MADE A PROFIT OF 50%

Step-by-step explanation:

The new cost of butter = cost of the butter mixed

                               = (2 kg of butter which costs

                                   $8 per kg) + (3 kg of butter which costs $6 per kg)

                               = $16 + $18 = $34/5kg (as 5kg of butters were mixed)

New cost of butter = ($34/5 ) /kg = $6.8/kg

Now,accordig to the question,

250gram is sold at $2.55

1kg will be sold at    $ 10.2  

now, profit made in selling 1 kg of newly made butter is,

= selling price - cost price

= $10.2 -$2.55

= $3.4

Now, profit percentage = (profit*100)/cp

                                      = ($3.4*100)/$6.8

                                      = 50%

hence, the required profit percentage is 50.

hope it helps!
