Answer 1

Answer:

Selling price of the washing machine = ₹15600

Step-by-step explanation:

Given :

Cost price of the washing machine = ₹12000

Profit = 30%

To find :

The Selling price of the Washing machine

Taken :

To find the selling price of the washing machine use this formula -:

$\boxed{\tt{S.P.=\dfrac{100\%+P\%}{100\%}\times\:C.P.}}$

Where,

S.P. = Selling price

P% = Profit percentage

C.P. = Cost price

Solution :

$:\implies\tt{S.P.=\dfrac{100\%+30\%}{100\%}\times12000}$

$:\implies\tt{S.P.=\dfrac{130\%}{\cancel{100\%}}\times\cancel{12000}}$

$:\implies\tt{S.P.=130\%\times120}$

$:\implies\tt{S.P.=Rs.15600}$

So , the Selling price of the washing machine is ₹15600 .

Extra information :

▪︎To find the Selling price if loss use this formula -:

$\boxed{\tt{S.P.=\dfrac{100\%-L\%}{100\%}\times\:C.P.}}$

▪︎To find the cost price use this formula -:

If profit -:

$\boxed{\tt{C.P.=\dfrac{100\%}{100\%+P\%}\times\:S.P.}}$

If loss -:

$\boxed{\tt{C.P.=\dfrac{100\%}{100\%+L\%}\times\:S.P.}}$
