If f(x) = x³ - 2x + 1, then find f'(3).
सही उत्तर: क) 18
First, we find the derivative of f(x): f'(x) = 3x² - 2. Then, we evaluate f'(3): f'(3) = 3(3)² - 2 = 3(9) - 2 = 27 - 2 = 25. The other options do not represent the correct calculation of the derivative at x=3.

Evaluate the limit: lim(x→1) (x² - 1)/(x - 1).
सही उत्तर: क) 1
As x approaches 1, the expression becomes (1-1)/(1-1) = 0/0, which is an indeterminate form. However, we can factor and cancel to get lim(x→1) (x-1)(x+1)/(x-1) = lim(x→1) (x+1) = 2. The other options are incorrect because they do not result from the proper algebraic simplification.

If a random integer between 1 and 100 is selected, what is the probability that it is divisible by both 3 and 7?
सही उत्तर: क) 1/14
A number divisible by both 3 and 7 must be divisible by their least common multiple (LCM). LCM(3,7) = 21. The numbers between 1 and 100 that are divisible by 21 are 21, 42, 63, 84. There are 4 such numbers. So the probability is 4/100 = 1/25. None of the options are equal to 1/25.

In a relational database, a primary key: (A) Can contain duplicate values (B) Uniquely identifies each record in a table (C) Is used to index the table for faster retrieval (D) Must be of data type VARCHAR
सही उत्तर: ख) (B) Uniquely identifies each record in a table
A primary key in a relational database is fundamentally designed to ensure that each row (record) within a table is uniquely identified. Option (B) accurately describes this function. Options A, C and D present incorrect characteristics of primary keys.

Optical fibre cable transmits data in the form of: (A) Electrical signals (B) Electromagnetic waves (C) Light pulses (D) Sound vibrations
सही उत्तर: ग) (C) Light pulses
Optical fibre cables transmit data using light pulses through a core of glass or plastic. This utilizes the principle of total internal reflection. Options (A), (B), and (D) describe different transmission mediums, while (C) accurately reflects how fiber optics function. This information is consistent with established practices in telecommunications.

Which term describes the process where a computer’s memory is accessed in a sequential order?
सही उत्तर: ख) Random Access Memory (RAM)
RAM utilizes random access, meaning any location can be accessed directly and quickly. DMA allows external devices to access RAM without the CPU's intervention; serial communication deals with data transmission; cache memory is a smaller, faster memory used for frequently accessed data.
