Question

P, Q, R and S are to be uniquely coded using $\alpha$ and $\beta$. If P is coded as $\alpha \alpha$ and $Q$ as $\alpha \beta$. then $R$ and $S$, respectively, can be coded as ____.

• A. $\beta \alpha$ and $\beta \beta$
• B. $\alpha \beta$ and $\beta \beta$
• C. $\beta \alpha$ and $\alpha \beta$
• D. $\beta \beta$ and $\alpha \alpha$

Answer 1

The correct option is A $\beta \alpha$ and $\beta \beta$

$\beta \alpha$ and $\beta \beta$
Given, Code of P = $\alpha \alpha$
Code of $Q=\alpha \beta$

then Code of $R=\beta \alpha$
and Code of $S=\beta \beta$
