Answer:
mg of powder 1 and
mg of powder 2
Explanation:
Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture
Total weight of vitamin B1 in the mixture is equal to
mg
Total weight of vitamin B2 in the mixture is equal to
mg
Equation 1

Equation 2

Let us simplify the above two equations, we will get


Substituting value of X in equation 2 we get
