Answer 1

Given:

• Selling Price of an article= 720 rupees
• Loss% of an article = 10%

To Find:

• Cost Price of an article = ?

Solution:

We are given,

• S. P. = 720 rupees
• Loss% = 10%

Formula to be used:

$\sf \pink \implies \: cost \: price = \frac{selling \: price \times 100}{100 - loss \: percent }$

Substitute the values

$\implies \sf \: cost \: price = \frac{720 \times 100}{100 - 10} \\ \\ \implies \sf \: cost \: price = \frac{720 \times 100}{90} \\ \\ \implies \sf \: cost \: price = 800 \: rupees$

Hence,cost price of an article is 800 rupees.

Answer 2

Answer:

Given :

• Selling Price of an article= 720 rupees
• Loss% of an article = 10%

To Find :

• Cost Price of an article = ?

Solution :

We are given,

• S. P. = 720 rupees
• Loss% = 10%

Formula to be used :

Cost price :-

= ( selling price x 100 ) / ( 100 - loss % )

C.P. = ( 720 x 100 ) / ( 100 - 10 )

• 72000/90
• 7200/9
• 800

Hence, Cost price = Rs.800
