Answer:

Option A

Step-by-step explanation:

Here the fat by volume of three different grade is equal to 1.5% grade.

Thus, if we write the above relationship mathematically we get -

1% of x + 2% of y+ 3[/tex]% of z= 1.5% of (x+y+z)

On solving the above equation, we get -

x+2y+3z=1.5x+1.5y+1.5z\\0.5x=(2y-1.5y)+(3z-1.5z)\\[tex]x= 2*0.5y+2*1.5z\\ x= y+3z

Hence, option A is correct
