4 SP = 5 CP
then SP / CP = 5/4
means SP = 5 and CP = 4
so profit =[ (5-4)/4]× 100 = (1/4)×100
= 25%

s7388: there is no attachment option.

HitheshRamesh7: send through mail

s7388: if i don't like to share my mail id then..?

HitheshRamesh7: then simple i have sent you a friend request in brainly accept and send

s7388: ignoring bit complex calculation i am providing simple concept

HitheshRamesh7: where

s7388: if particle travels in two equal time interval and distance covered in unequal speed then average speed will be (2×V1×V2)/V1 + V2

s7388: here first find the V2 =average speed of 4.5m/s and 7.5m/s =( 4.5+7.5)/2 = 6m/s now this value will work as a V2

s7388: now V1 = 3 and V2 = 6 now put these values in formula so we get (2×3×6)/(3+6) = 36/9 = 4 m/s

s7388: there are two other methods also but those are very long and calculative.

Answer:

25 %

Step-by-step explanation:

Since, the selling price of 4 articles is equal to the cost price of 5 articles.

⇒ S.P. of 4 = C.P of 5,

$\implies \frac{\text{S.P.}}{\text{C.P.}}=\frac{5}{4}$

Let the selling price is 5x and cost price is 4x,

Where, x is any number,

Since, S.P. > C.P.

Thus, the profit = Selling price - Cost price = 5x - 4x = x,

Now,

$\text{Profit percentage}=\frac{\text{Profit}}{\text{Cost price }}\times 100$

$=\frac{x}{4x}\times 100$

$=\frac{100}{4}=25\%$
