Answer 2

$\bf\large \underbrace\red{Answer:}$

Time taken by first pipe to fill = 12 hours

So, In 1 hour, pool filled = 1/ 12

Time taken by Second pipe to fill = 18 hours

So, In 1 hour, pool filled = 1/ 18

In 1 hour, both pipes together fill

$\bf\implies \:\dfrac{1}{12} + \dfrac{1}{18}$

$\bf\implies \:\dfrac{3 + 2}{36}$

$\bf\implies \:\dfrac{5}{36}$

So, time taken by pipes to fill the pool together = 36/5 hours

⇛ Time taken = 7 hours 12 min

So it means pool will be filled by 3 : 12 pm.
