Question

A coconut produces $350\text{mL}$ of juice on an average. A fruit vendor gets an order to serve $1050\text{mL}$ coconut juice. Choose the correct option regarding this situation.

• A. Number of coconuts is the dependent variable and quantity of juice is the independent variable.
• B. Number of coconuts is the independent variable and quantity of juice is the dependent variable.

Answer 1

The correct option is B Number of coconuts is the independent variable and quantity of juice is the dependent variable.

A coconut produces $350\text{mL}$ of juice.
$\therefore$ The quantity of coconut juice produced is a multiple of the number of coconuts cracked.
To produce $1050\text{mL}=3\times 350\text{mL}$ coconut juice, $3$ coconuts need to be cracked.

$\therefore$ We must first take $3$ coconuts, which is an independent variable, then we can extract the required amount of juice, which is dependent upon the number of coconuts cracked.
