If 20 litres of mixture containing 85% milk is mixed with 25 litres of another mixture, Then the resultant mixture has 60% milk. Find the percentage of milk in the second mixture.

Milk in first mix $= \frac{85}{100} \times 20$
$= 17$ ltrs
Milk in $2^{n d}$ mix $= \frac{x}{100} \times 25 = \frac{x}{4}$
Total milk $= \frac{60}{100} (45) = 27$ ltrs
So $17 + \frac{x}{4} = 27$
$\Rightarrow \frac{x}{4} = 10$
$\Rightarrow x = 40 %$ .

If 20 litres of mixture containing 85% milk is mixed with 25 litres of another mixture, Then the resultant mixture has 60% milk. Find the percentage of milk in the second mixture.

Milk in first mix =85100×20=17 ltrsMilk in 2nd mix =x100×25=x4Total milk =60100(45)=27 ltrsSo 17+x4=27⇒x4=10⇒x=40%.
