Answer 1

Step-by-step explanation:

$\Huge{\mathfrak{ Answer }}$

Given

Average price of 12 toy cars + 12 books - Rs 600

Solution

Let the price of toy car be x

Then the price of book will be 2x

Given

$\frac{12(x) + 12(2x)}{24} = 600 \\ \\ \frac{12x + 24x}{24} = 600 \\ \\ \frac{36x}{24} = 600 \\ \\ 36x = 24 \times 600 \\ \\ x = 24 \times 600 \div 36 \\ \\ x = 400$

So, cost of toy car = Rs 400

And cost of book = Rs 800

Now

total cost = 3(400)+2(800)

= Rs ( 1200+ 1600)

= Rs 2800

hope it helps ✌
