Question

On selling 18 toys at RS 840 , there is a loss equal to the cost price of 6 toys . The cost price of 6 toys is ?

Answer 1

Answer:

420

Step-by-step explanation:

Here the loss + the total money made selling = cost price of 18 toys.

let the cost price of one toy = x

total loss = 6x

total money made selling = 840

18x = 6x + 840.(subract both sides by 6x)

12x = 840

840/12 = x

70 = x

cost price of 6 toys  = 420

Answer 2

On selling 18 toys at RS 840 , there is a loss equal to the cost price of 6 toys . The cost price of 6 toys is ?

$\huge\bold\red{ loss = Cp - SP } \:$

let cp of toy be X

loss = price of 6 toys = 6x

6x = 18x - 840

12x = 840

$\boxed{x = \frac{840}{12} }$

$\bold\green{ 70 }$

$\underline\bold\blue{ cp \: of\: 6 :\ toys :\ is :\ 420}$

as cp of 1 toy was 70 .

we need to find CP of 6 toys .

applying direct proportion we get :

cp of 6 toys will be 70×6

ie. 420
