please answer this question​

Answer 1

Answer:

cost price = 4x

selling price = 5x

profit % = (sp - cp)/ cp × 100

= (5x - 4x) / 4x × 100

= (x ×100) / 4x

= 25

Hence profit% is 25

Step-by-step explanation:

Answer 2

• Option (c) 25% is the correct option.

Given :–

• The ratio of cost price and selling price = 4 : 5.

To Find :–

• The profit percent.

Solution :–

Let,

The cost price be 4x.

The selling price be 5x.

We know that,

$\tt \blue{\boxed{\red{Profit \: percent = \dfrac{Selling \: Price - Cost \: Price}{Cost \: Price} \times 100}}}$

Here given that,

• Cost price (C.P.) = 4x.
• Selling price (S.P.) = 5x.

Now,

$\mapsto \dfrac{5x - \cancel{4x}}{ \cancel{4x}} \times 100$

$\mapsto \dfrac{1x \times 100}{4x}$

$\mapsto \cancel{ \dfrac{x \times 100}{4 \times x}}$

$\mapsto 25\%$

Hence,

The profit percent is 25%.

So, the correct option is (c) 25%.

Additional Information :–

Some more formulas :-

1. $Profit = S.P. - C.P.$

2. $Loss = C.P. - S.P.$

3. $Profit \% = \dfrac{S.P. - C.P.}{C.P.} \times 100$

4. $Loss \% = \dfrac{C.P. - S.P.}{C.P.} \times 100$

5. $S.P. = \dfrac{100 + Profit\%}{100} \times C.P.$

6. $S.P. = \dfrac{100 - Loss\%}{100} \times C.P.$

7. $C.P. = \dfrac{100}{100 + Profit\%} \times S.P.$

8. $C.P. = \dfrac{100}{100 - Loss\%} \times S.P.$
