Answer 1

Answer:-

$\red{\bigstar}$ There will be Loss of the shopkeeper and by $\large\leadsto\boxed{\tt\purple{10.71 \%}}$

• Given:-

• Shopkeeper buys 15 oranges for Rs. 21

• Sells them at 20 oranges for Rs. 25

• To Find:-

• Gain or Loss %

• Solution:-

★ $\large\underline{\underline{\rm\pink{C.P:-}}}$

Given that,

• Cost Price of 15 oranges = Rs. 21

➠ Cost Price of 1 orange = $\sf \dfrac{21}{15}$

➠ $\bf\blue{Rs. \: 1.4}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large\underline{\underline{\rm\pink{S.P:-}}}$

Given that,

Selling Price of 20 oranges = Rs. 25

➠ Selling Price of 1 orange = $\sf \dfrac{25}{20}$

➠ $\bf\blue{Rs. \: 1.25}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Here,

C.P > S.P

Hence,

LOSS

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

We know,

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{Loss = C.P - S.P}}}$

➠ $\sf Loss = 1.4 - 1.25$

➠ $\bf\blue{Loss = Rs. \: 0.15}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Also,

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{Loss \% = \dfrac{Loss}{C.P} \times 100}}}$

➠ $\sf Loss \% = \dfrac{0.15}{1.4} \times 100$

➠ $\sf Loss \% = \dfrac{15}{1.4}$

★ $\large{\bf\red{Loss \% = 10.71 \%}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, there is a loss of 10.71%.

Answer 2

Answer:

Given :-

• A shopkeeper buys 15 oranges for Rs 21 and sells them at 20 oranges for Rs 25.

To Find :-

• Gain or lose percentage.

Solution :-

✦ For Cost price :-

➣ Number of oranges = 15

➣ Cost price = Rs 21

➣ Cost price of each oranges,

⇒ $\dfrac{21}{15}$

⇒ $\dfrac{7}{5}$ ➠ Rs 1.4

✦ For selling price :-

➯ Number of oranges = 20

➯ Selling price = Rs 25

➯ Selling price of each oranges,

⇒ $\dfrac{25}{20}$

⇒ $\dfrac{5}{4}$ ➠ Rs 1.25

So, we can understand that it is loss.

Now, we have to use the loss formula,

$\boxed{\bold{\small{Loss\: =\: Cost\: Price\: -\: Selling\: Price}}}$

By using the formula we get,

⇒ Loss = 1.4 - 1.25

➠ Loss = 0.15

So, loss percentage will be,

$\boxed{\bold{\small{Loss\%\: = \dfrac{Loss}{Cost\: Price} × 100}}}$

Again, by using the formula we get,

⇒ Loss% = $\dfrac{0.15}{1.4}$ × 100

⇒ Loss% = $\dfrac{15}{1.4}$

➠ Loss% = 10.71%

∴ There will be a loss of 10.71% .
