Question 90

Computer Awareness Boolean algebra Hard

The simplified form of Boolean Expression: \( \overline{\mathrm{A}} \mathrm{BC}+\mathrm{ABC} \) is

(A) AC
(B) AB
(C) BC
(D) 0
โœ“ Correct Answer: Option C Verified Solution

๐Ÿ“˜ Step-by-Step Solution & Detailed Explanation:

The given Boolean expression is: \[ \overline{A}BC + ABC \] Step 1: Factor Out Common Terms
Observe that both terms have \( BC \) in common: \[ BC (\overline{A} + A) \] Step 2: Apply Boolean Identity
Using the complement property: \[ \overline{A} + A = 1 \] we simplify: \[ BC \cdot 1 = BC \] Final Answer: \( BC \)
Thus, the simplified form of the Boolean expression \(\overline{A}BC + ABC\) is \(BC\).
