Answer 1

From the given table we can see that mixture of 2 cups of blue paint and 10 cups of yellow paint produced green cups.

So , the ratio of yellow to blue is , $R=\dfrac{10}{2}=5$.

We need to find , the number of cups of yellow paint should we mix with 1 cup of blue paint to make the same shade of green.

We know , produce same shade ratio should be constant.

Let , cups of yellow shade is x .

$\dfrac{x}{1}=5\\\\x=5$

Therefore , cups of yellow shades required are 5.

Hence, this is the required solution.
