1. (c) The above series is actually the prime no. ones. Here each prime no. starting from 11 would get multiplied by 2. 11 × 2 = 22 13 × 2 = 26 17 × 2 = 34 ………… 41 × 2 = 82 43 × 2 = 86 Hence, option (c) is correct.
- (b) The above series follows the pattern given below :- 1 × 1 = 1 2 × 2 = 4 4 × 4 = 16 8 × 8 = 64 …………… 64 × 64 = 4096 Hence, option (b) is correct.
5. (e) In the above series, the numbers follows this pattern:-
9 + 5 = 14; 14 – 2 =12
12 + 5 = 17; 17 – 2 = 15
15 + 5 = 20; 20 –2 = 18
18 + 5 = 23; 23 – 2 = 21
Hence, Option (e) is the answer. Here actual answer is 23, 21
- (c) In the above series, the next term is derived from previous one in certain pattern: –
=> 4 = 1 × 1 + 3
14 = 4 × 2 + 6
51 = 14 × 3 + 9 and so on.
Here, consider term 218Þ
=> Now according to above pattern,
=> 51 × 4 + 12
=>216 should come, but 218 is being wrongly inserted
Hence, option (c) is correct
10. (c); In the above mentioned series, the next term is derived from previous one by dividing a no. following a certain pattern.
=>630 3.5 = 180
=>180 3 = 60
=>60 2.5 = 24
Here instead of 26, 24 should come in above series.
Hence, option (c) is correct.

I) Only B is sitting between C and E. D is sitting between C and A.
II) Neither E nor C can sit on the left of D.
From – I : R is lighter than only Q and T. Thus I alone is not sufficient to answer.
From – II : P is lighter than R and heavier than S. But nothing is given about Q and T. So II alone is not sufficient.
From I and II : Q and T <— R <— P <— S
So, S is the lightest. Thus, I and II both are necessary to
It is clear that Rekha’s is sister of Nidhi. So, I alone is sufficient.
From – II : Nothing is mentioned about Rekha. So we can’t find the relationship. Thus, II alone is not sufficient.
From – I : P <— N & O and R <— M & P
So, I alone is not sufficient.
Form – II : R & O <— M <— N & P , also O didn’t got
highest marks and N didn’t got the least marks. Then,
R <— O <— M <— N <— P
So, P got the least marks, thus, II alone is sufficient to

Sol. Fifth generation computers are in developing stage which is based on the artificial intelligence.
Sol. Information is an organised or classified data which has some meaningful values for the receiver.
Sol. Both terms are used to refer to internal storage space on a computer. Memory, usually referred to as Random Access Memory (RAM), is the place where an application loads its data during processing, while a hard disk drive (HDD) is usually the place where data is stored for long or short term retention.
Sol. An analog computer is a form of computer that uses the continuously changeable aspects of physical phenomena such as voltage.
Sol. A typical CPU has mainly these components: The first is the arithmetic logic unit (ALU), which performs simple arithmetic and logical operations. Second is the control unit (CU), which manages the various components of the computer. It reads and interprets instructions from memory and transforms them into a series of signals to activate other parts of the computer. The control unit calls upon the arithmetic logic unit to perform the necessary calculations.
Sol. Logical errors occur when the program runs without crashing, but produces an incorrect result. The error is caused by a mistake in the program’s logic.
Sol. A database is a collection of information that is organized so that it can easily be accessed, managed, and updated. In one view, databases can be classified according to types of content: bibliographic, full-text, numeric, and images.
Sol. A wide area network (WAN) is a telecommunications network or computer network that extends over a large geographical distance.
Sol. Web browser is a software application used to establish a connection with the server, locate, retrieve and display content from the World Wide Web, including Web pages, images, video and other files. Examples of web browser are Internet Explorer, Safari, Firefox etc.
Sol. A supercomputer is a computer with a high-level computational capacity and they are used for scientific computations.
Sol. Booting is a startup sequence that starts the operating system of a computer when it is turned on. A boot sequence is the initial set of operations that the computer performs when it is switched on. Every computer has a boot sequence. It also ensures the components of the computer are operating and connected properly.
Sol. Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which are data structures that contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. Java is an object oriented programing language.
Sol. A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function, and typically executes the program’s instructions in a central processing unit.
Sol. ADP is a data file format created by Microsoft Access.
Sol. Spyware is a software that enables a user to obtain covert information about another’s computer activities by transmitting data covertly from their hard drive.
