Juhi sells a washing machine for rs 13500 she loses 20%.what is the price she brought

Answer 1

✬ Cost Price = Rs 16875 ✬

Step-by-step explanation:

Given:

• Juhi sells a washing machine for Rs 13500.
• Loss percent made on washing machine is 20%.

To Find:

• What is the Cost Price of washing machine?

Solution: Here we have

• S.P = Rs 13500
• Loss % = 20%
• C.P = To be calculated

As we know that to find C.P when S.P & loss % are given the formula is :-

★ C.P = ( S.P $\times$ 100/100 – Loss% ) ★

$\implies{\rm }$ C.P = ( 13500 $\times$ 100/100 – 20 )

$\implies{\rm }$ C.P = ( 13500 $\times$ 100/80 )

$\implies{\rm }$ C.P = ( 1350000/80 )

$\implies{\rm }$ C.P = Rs 16875

Hence, cost price of washing machine is Rs 16875.

★ Other Formulae ★

→ Profit % = (Profit/C.P x 100) %

→ Loss % = (Loss/C.P x 100) %

Answer 2

Given ,

Selling price (SP) = 13500

Loss % = 20 %

We know that ,

$\large \sf \fbox{Loss \: \% = \frac{cp - sp}{cp} \times 100}$

Thus ,

$\sf \mapsto 20 = \frac{CP - 13500}{CP} \times 100 \\ \\\sf \mapsto 20CP = 100CP - 1350000 \\ \\\sf \mapsto 100CP - 20CP = 1350000 \\ \\ \sf \mapsto 80CP= 1350000 \\ \\ \sf \mapsto CP = \frac{1350000}{80} \\ \\ \sf \mapsto CP = 16875$

$\therefore \sf \underline{The \: cost \: price \: of \: washing \: machine \: is \: Rs \: 16875}$
