Question

The volume of water flowing through a pipe is as given below.



The flow rate of the water can be expressed as the ratio

• A. 1 : 4
• B. 5 : 1
• C. 4 : 1
• D. 1 : 5

Answer 1

The correct option is B 5 : 1


$\text{Volume of water flowing in 6 hours is 30 L}$

$\text{Volume of water flowing in 4 hours is 20 L}$

$\text{The volume of water flowing in 1 hour is}\text{5 times the hours taken.}$

$\text{Hence, every single hour 5 L of water}\text{flows through the pipe.}$

$\therefore \text{The flow rate of water}=\frac{5\text{litres}}{1\text{hour}}$

$\text{Representing this as a ratio, we get:}$

$\frac{5}{1}⟹5:1$

$\therefore \text{The flow rate of the water can be}$ $\text{expressed as 5:1}$
