Exactly 80 liters of 20% are needed.
Let quantity of 20% alcohol solution be added : x liters
Here is the work:
> x*20% + 40 * 50% = (x+40) * 30%
> x*0.2 + 40*0.5 = (x+40)*0.3 ..(converting percentages into decimal)
> 0.2x + 20 = 0.3x + 12
> 20-12 = 0.3x - 0.2x (Rearranging similar terms)
> 8 = 0.1 x
Hence x = 8/0.1
Ans 80 Litres

Answer:
a_s=4.8\times 10^{-2}~m^2
Explanation:
Given:
cross-sectional area of the bone, a=4.8 \times 10^{-4} ~m^2
the factor of up-scaling the dimensions, s=10
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled-up area is:
a_s=a\times s^2
a_s=[4.8 \times 10^{-4}]\times 10^2
a_s=4.8\times 10^{-2}~m^2
