CUET PG 2026 — Computer PYQ

CUET PG | Computer | 2026

Complement of $\overline{A + B}$

Choose the correct answer:

Explanation

Solution

To find the complement of an expression, we apply a bar over the entire expression and simplify using Boolean laws.

1. Set up the expression:

The given expression is $\overline{A + B}$ . Its complement is:

\overline{(\overline{A + B})}

2. Apply the Double Involution Law:

The Double Involution Law states that the complement of a complement of a variable (or expression) is the variable itself:

\overline{\overline{X}} = X

3. Simplify the expression:

Applying this law to our problem:

\overline{\overline{A + B}} = A + B

Note on De Morgan's Law (for comparison):

While not strictly needed to solve this specific "double bar" problem, De Morgan's laws are often used in these topics:

$\overline{A + B} = \bar{A} \cdot \bar{B}$
$\overline{A \cdot B} = \bar{A} + \bar{B}$

Final Answer:

The correct option is (c) $A + B$ .
