3 pipes take 12 hours
⇒ In 1 hour, the 3 pipes can fill 1/12 of the pool
2 of the pipes take 18 hours
⇒ in 1 hour, the 2 pipes can fill 1/18 of the pool
In 1 hour, the third pipe alone can fill :

Time needed :

Answer: It will take 36 hours for the third pipe to fill the pool.----------------------------------------------------------------------------------------
Your system could be anything, just remember that input should be half than the output.
So, y ≥ 1/2x
5y ≥ 5/2x
10y ≥ 5x
Hope this helps!
-21x^3 - 8x^3 = -29x^3
-7/4x^(1/2) - 0 = -7/4x^(1/2)
-6x^(1/4)
-12x^(-1/2)
12x^(-1/4)
14x^4
Therefore, the correct option is the 2nd one.
