Answer 1

Answer:

4533.33

$sp = 3400$

$\frac{(cp - sp)}{cp} \times 100 = 15$

$100cp - 340000 = 15cp$

$75cp = 340000$

$cp = 4533.33$

Answer 2

The cost price of the article = Rs. 4000

Given :

Sonu sold an article for Rs. 3400 and loss 15%

To find :

The cost price of the article

Solution :

Step 1 of 2 :

Form the equation to find the cost price of the article

Let the cost price of the article = Rs. C

Now it is given that Sonu sold an article for Rs. 3400 and loss 15%

By the given condition

$\displaystyle \sf{ C - \bigg(C \times \frac{15}{100} \bigg) = 3400}$

Step 2 of 2 :

Find the cost price of the article

$\displaystyle \sf{ C - \bigg(C \times \frac{15}{100} \bigg) = 3400}$

$\displaystyle \sf{ \implies C - \frac{15C}{100} = 3400 }$

$\displaystyle \sf{ \implies \frac{100C - 15C}{100} = 3400 }$

$\displaystyle \sf{ \implies \frac{85C}{100} = 3400 }$

$\displaystyle \sf{ \implies C= 3400 \times \frac{100}{85} }$

$\displaystyle \sf{ \implies C= 40 \times 100 }$

$\displaystyle \sf{ \implies C= 4000 }$

Hence cost price of the article = Rs. 4000
