Answer 1

Answer:

rat ko bata dugi Abhi kisi or se puch la

Answer 2

Let the price of toy car be x

Then the price of book will be 2x

Given

\begin{gathered}\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\end{gathered}

24

12(x)+12(2x)

=600

24

12x+24x

=600

24

36x

=600

36x=24×600

x=24×600÷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
