ISC Class 12 Computer Science Specimen Paper 2025 Questions

Some of the sample questions given in the specimen paper is being provided below. Students can check the complete specimen paper questions and solutions in the above PDF.

Question 1

(i) The compliment of the Boolean expression Aꞌ • (B • Cꞌ + Bꞌ • C) (Application) [1]
(a) Aꞌ • (B+C+Bꞌ +C)
(b) A+ (B+Cꞌ) •(B+Cꞌ)
(c) A+(Bꞌ +C) • (B+Cꞌ)
(d) Aꞌ • (Bꞌ +Cꞌ +Bꞌ •C)

(ii) Given below are two statements marked Assertion and Reason. Read the two statements carefully and choose the correct option.
Assertion: Recursion utilises more memory as compared to iteration.
Reason: Time complexity of recursion is higher due to the overhead of maintaining the function call stack. (Analysis [1]
(a) Both Assertion and Reason are true and Reason is the correct explanation for Assertion.
(b) Both Assertion and Reason are true but Reason is not the correct explanation for Assertion.
(c) Assertion is true and Reason is false.
(d) Assertion is false and Reason is true.

(iii) According to the Principle of duality, the Boolean equation
(Aꞌ + B) • (1 + B) = Aꞌ + B will be equivalent to: (Application)[1]
(a) (A + Bꞌ) • (0 + B) = A + Bꞌ
(b) (Aꞌ • B) + (0 • B) = Aꞌ • B
(c) (Aꞌ • B) + (0 • B) = Aꞌ + B
(d) (Aꞌ + B) • (0 + B) = Aꞌ + B

(iv) Distributive law states that: (Recall) [1]
(a) A + B • C = (A + B) • (A +C)
(b) A + ( A • B) = A
(c) A • (B + C) = (A • B) + (B • C)
(d) A + B • C = A • B + A • C

(v) The complement of the reduced expression of F(A,B) = Σ (0,1,2,3) is: (Application) [1]
(a) 1
(b) A • B
(c) 0
(d) Aꞌ + Bꞌ
