Answer 1

step by step explanation

Answer 2

Given:

SP = 820  Profit = 25%

To find:

CP

Solution:

Given SP = Selling Price = 820 and profit = 25%

Given that profit = 25% which means

On 100 Rs cost price the profit is 25 Rs

Then Selling Price = 100 + 25 = 125 Rs

For 125  Selling Price the Cost Price = 100

For 820 Selling Price the Cost Price  =  ?

Let x be the required cost price

Here 125 : 100 = 820 :  x  

⇒  125/100 = 820/x

⇒  x = (100/125)×820 = 656

Therefore,

The cost price = 656 Rs
