Answer 2

Answer:

☆ Given ☆

$\textsf{Harish bought a gas - chullah for 900 rupees}$

$\textsf{At 5 percent profit he sold it to Archana}$

$\textsf{Archana later sold it to Babita at the loss of 20 percent}$

☆ To find ☆

$\textsf{For how much did Babita get it}$

☆ Taken ☆

To find selling price by profit given:

$\boxed{SP=\frac{100+P}{100}×CP}$

Where,

SP = Selling price

P = Profit percent

CP = Cost price

To find selling price by loss given:

$\boxed{SP=\frac{100-L}{100}×CP}$

Where,

SP = Selling price

L = Loss percent

CP = Cost price

☆ Concept ☆

First find how much does Harish sold to Archana .

Then , the amount will come will be the CP . Then , find in how much does Archana sold the gas - cuhla to Babita .

☆ Solution ☆

For how much does Harish sold to Archana:

$Taken,SP=\frac{100+P}{100}×CP$

$\implies{SP=\frac{100+5}{100}×900}$

$\implies{SP=\frac{105}{100}×900}$

$\implies{SP=105×9}$

$\implies{SP=945\:rupees}$

For how much does Archana sold to Babita:

$Taken,SP=\frac{100-L}{100}×CP$

$\implies{SP=\frac{100-20}{100}×945}$

$\implies{SP=\frac{80}{100}×945}$

$\implies{SP=80×9.45}$

$\implies{SP=756\:rupees}$

☆ Answer ☆

So , Babita got the gas - chula at ₹ 756 .

☆ Extra information ☆

To find profit percent:

$Pr=\frac{P×100}{CP}$

Where,

Pr = Profit percent

P = Profit

CP = Cost price

To find loss percent:

$Lr=\frac{L×100}{CP}$

Where,

Lr = Loss percent

L = Loss

CP = Cost price

To find cost price at loss and profit:

At profit:

$CP=\frac{100}{100+Pr}×SP$

At loss:

$CP=\frac{100}{100-Lr}×SP$

Where,

CP = Cost price

Pr = Profit percent

Lr = Loss percent

SP = Selling price
