Answer 2

Answer:

The profit percentage is 3.5%

Step-by-step explanation:

Given,

The cost price of an item is $ 840.

Therefore cost price = $ 840

Now the mark up is 15 %

So, selling price of the item is

$840 + 15\% \: of \: 840 = 840 + \frac{15}{100} \times 840 \\ = 840 + \frac{3}{2} \times 84 \\ = 840 + 3 \times 42 \\ = 840 +12 6 \\ = 966$

Now discount amount is 10%.

So after discount selling price will be

$966 - 966 \times \frac{10}{100} \\ = 966 - 96.6 \\ = 869.4$

Final selling price is $ 869.4.

We know,

profit=Selling price - cost price

$= 869.4 - 840 \\ = 29.4$

Now, Cost price 840 means 100%

By Unitary method,

1 means $\frac{100}{840} \%$

29.4 means

$\frac{100}{840} \times 29.4 \\ = \frac{100}{840} \times \frac{294}{10} \\ = \frac{294}{84} \\ = 3.5\%$
