Question 77 (ii)

From the following table x and y are in direct proportion.

• A. x and y are in direct proportion.
• B. x and y are not in direct proportion.

Answer 1

The correct option is A

x and y are in direct proportion.

In direct proportion, $\frac{x}{y}=k\left(constant\right)$

$\Rightarrow \frac{x}{y}=\frac{4}{24},\frac{7}{42},\frac{10}{60},\frac{16}{96}i.e.\frac{1}{6},\frac{1}{6},\frac{1}{6},\frac{1}{6}$,

Since $\frac{x}{y}=\frac{1}{6}\left(constant\right)$ hence x and y are in direct proportion.
