Answer:
Earth will complete more revolutions than Saturn.
Explanation:
It takes one year for the Earth to complete one revolution around the Sun. Our calendar is based on this fact, but some planets may finish one revolution around the Sun faster than us, while other planets will take more time to do it. For example, it takes Saturn 29 years to complete one revolution around the Sun, on the meantime, the Earth will have completed 29 revolutions.

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

Ok, so first you have to count le 15% off. It means you pay 85% of the price
0,85•65= 55,25$
Second, you take the 10$ off
55,25-10=45,25$
Third, you have know what percentage of the original price you paid
45,25 divided by 65 =0,6962
So you actually paid 69,62% of the original price
