Question

Find the proportionality constant between amount of milk and tea.

• A. $\frac{1}{4}$
• B. $\frac{1}{3}$
• C. $\frac{1}{2}$
• D. $1$

Answer 1

The correct option is C $\frac{1}{2}$

Given that,

All ingredients in making tea are in proportion with amount of tea

hence, amount of milk is directly proportion to amount of tea

$\therefore \frac{amountofmilk}{amountoftea}=K$

where $K$ is constant of proportionality

$\therefore K=\frac{4}{8}$ $⟹K=\frac{1}{2}$

Answer is option C
