Answer: There is 12.6 pounds of ingredient B present.
Explanation:
Since we have given that
Ratio of ingredients A, B and C = 2:3:5
Weight of ingredient A = 2x
Weight of ingredient B = 3x
Weight of ingredient C = 5x
Total net weight = 42 pounds
According to question, we get that
![2x+3x+5x=42\\\\10x=42\\\\x=(42)/(10)\\\\x=4.2\ pounds](https://img.qammunity.org/2020/formulas/mathematics/high-school/pu31504gg139zki0qv4lc3ptexwricgjwp.png)
So, Weight of ingredient B is given by
![3x=3* 4.2=12.6\ pounds](https://img.qammunity.org/2020/formulas/mathematics/high-school/639xe3oetua2xs2n6oxgze89iy7ckrv886.png)
Hence, there is 12.6 pounds of ingredient B present.
