Answer 1

Given

jenny mixed 4kg of mixed nuts containing 16% of peanuts with 12kg of mixed nuts containing 40% of peanuts .

Find

Percent in the new mixture of peanuts

Step-by-step explanation

we are given 4kg of mixed nuts containing 16% of peanuts

Amount of quantity =

`(percentage)/(100)* totalamount`

so,

`(16)/(100)*4=0.64kg`

and also 12kg of mixed nuts containing 40% of peanuts .

so,

`(40)/(100)*12=4.8kg`

so,total weight

`0.64+4.80=5.44kg`

let total mass pf mixture containing x % peanuts.

so,

`\begin{gathered} (5.44)/(16)=(x)/(100) \\ 34=x \end{gathered}`

Final Answer

Percent in the new mixture of peanuts = 34%
