Answer :
Answer: 1250 kg.
Step-by-step explanation:
Let x = mass of product A.
y=mass of product B
Then , According to the given statement , we have
[tex]0.3x+0.7y=2000-------------(1)\\\\x=3y-----------(2)[/tex]
Put value of x from (2) in (1) ,we get
[tex]0.3(3y)+0.7y=2000[/tex]
[tex]0.9y+0.7y=2000[/tex]
[tex]1.6y=2000[/tex]
[tex]y=\dfrac{2000}{1.6}=\dfrac{20000}{16}=1250[/tex]
Put value of y in (2) ,we get x= 3(1250)=3750 =mass of product A
Therefore, the mass of product B =1250 kg.
