Answer:

9 + 10 = 19

Explanation:

So uh my brother pulls this stuff on me saying 9 + 10 = 21 because if you add 9 + 10 you get 19. Then you add 2 because you have 2 numbers. So 21. I don't know why people do this, it's funny but like, why.

How many liters of 60% alcohol solution should be added to 40 liters of a 20% alcohol solution to make a 50% solution?
IgorLugansk [536]

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
