The 3% milk quantity to be mixed is 15 liters and the the 15% cream quantity to be mixed is 5 liters

Step-by-step explanation:

The question is

Milk and cream contain different percents of butterfat. How much 3% milk needs to be mixed with how much 15% cream go give 20 L of 6% cream?

Let

x -----> the 3% milk quantity to be mixed

y -----> the 15% cream quantity to be mixed

we know that

-----> equation A

Multiply by 100 both sides

-----> equation B

substitute equation A in equation B and solve for y

Find the value of x (equation A)

therefore

The 3% milk quantity to be mixed is 15 liters and the the 15% cream quantity to be mixed is 5 liters

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
