Answer 1

Let the CP be Rs a

Profit = 30% of a

= 30a/100

= 3a/10

SP = CP +Profit

=> 390 = a + 3a/10

=> 390 = 13a/10

=> 3900=13a

=> a = Rs 300

Cost Price of toy car = Rs 300

Answer 2

Answer:

The cost Price of the toy is Rs. 300.

Step-by-step explanation:

Given :

Selling price of the toy car = Rs. 390

Profit made = 30%

To find :

The cost price of the toy car

Solution :

Here :

• Selling Price = Rs. 390
• Profit = 30%
• Cost Price = ??

$\bigstar{\boxed{\sf\:{CP = \frac{100}{(100 + profit\%)} \times SP}}}$

$\sf{\longrightarrow}\: CP = \dfrac{100}{(100 + 30\%)} \times 390\\ \\ \sf{\longrightarrow}\: CP = \dfrac{100}{130} \times 390 \\ \\ \sf{\longrightarrow}\: CP = \dfrac{39000}{130} \\ \\ \sf{\longrightarrow}\: CP = 300$

Cost Price = Rs. 300

$\therefore$ The cost Price of the toy is Rs. 300.
