Answer: Amount of 35% solution required = 100 milliliters

Amount of 87% solution required = 30 milliliters

Step-by-step explanation:

Given: Total solution required = 130 milliliters

Let x = Amount of 35% solution (in milliliters).

Then, Amount of 87% solution required = 130 - x

As per given,

Concentration = 0.35x +0.87(130-x)=0.47(130)

$0.35x +113.1-0.87x=61.1\\\\\Rightarrow\ -0.87x+0.35x=61.1-113.1\\\\\Rightarrow\ -0.52 x= -52\\\\\Rightarrow\ x=\dfrac{52}{0.52}=100$

Hence, Amount of 35% solution required = 100 milliliters

Amount of 87% solution required = 130-100 milliliters =30 milliliters
