Answer 2

Answer:

Cost price of toy is 810

Step-by-step explanation:

Given that

Selling of toy is at 729

Loss is of 10%

to find cost price

Solution

As we know that

$selling \: price = cost \: price - loss$

hence

$loss = \frac{10}{100} \times cost \: price$

$selling \: price = cost \: price - \frac{10}{100} \times cost \: price$

by taking cost price common

$729 = cost \: price(1 - \frac{1}{10} )$

$729 \times \frac{10}{9} = cost \: price$

by solving we get

$cost \: price = 810$

Hence cost price of toy is 810.
