B)

C)

D)
Layer Area Network
LAN stands for Local Area Network. It refers to a computer network that connects devices within a limited geographic area such as a home, office, school, or building.

Which term of the AP 5, 9, 13, 17, _________ is 81?
A)
81
B)
93
C)
101
D)
110
The sequence 5, 9, 13, 17, ... is an arithmetic progression (AP) with first term a = 5 and common difference d = 4.
The nth term of an AP is:
Tn = a + (n - 1)d
Given Tn = 81:
81 = 5 + (n - 1)4
81 - 5 = 4(n - 1)
76 = 4(n - 1)
n - 1 = 19
n = 20
So, 81 is the 20th term. The term value in the options that correctly corresponds to the continuation is 93? Wait—looking at the options, the question is asking which term (numbered term) is 81, but the options are values, not term numbers. In such MCQs, the intended question is usually about the term number or the next matching value. However, mathematically, 81 is the 20th term, and the 20th term value is 81, which is not listed among the options. Since the options do not match the correct result, the provided choices appear inconsistent. Therefore, the question as written cannot be solved reliably from the options.
Insulin was invented by-
A)
Ronald Ross
B)
Frederick Banting
C)
Edward Jenner
D)
Selman Waksman
Insulin was discovered/invented by Frederick Banting (along with Charles Best). Banting is the correct option. The other options are incorrect: Ronald Ross discovered the malaria parasite transmission by mosquitoes, Edward Jenner developed the smallpox vaccine, and Selman Waksman discovered streptomycin.
The length of the longest pole that can be put in a room of dimension (10m × 10m × 5m) is -
A)
10 m
B)
12 m
C)
15 m
D)
16 m
The longest pole that can fit in a rectangular room is the space diagonal of the room. For dimensions 10 m × 10 m × 5 m, the diagonal is √(10² + 10² + 5²) = √(100 + 100 + 25) = √225 = 15 m. So the correct length is 15 m, which corresponds to option (c). The other options are smaller than the actual maximum possible length.
A loan Rs. 3,12,000 is returned in three equal annual instalments of Rs. 1,10,000 each. The total interest charged is -
A)
Rs. 3,30,000
B)
Rs. 1,04,000
C)
Rs. 18,000
D)
Rs. 19,970
The borrower repays a total of 3 equal instalments of Rs. 1,10,000 each, so total repayment = 3 × 1,10,000 = Rs. 3,30,000. The original loan was Rs. 3,12,000. Therefore, total interest charged = 3,30,000 − 3,12,000 = Rs. 18,000. Hence, option (c) is correct.

A)
Electrocardiograph
B)

- (b) Anti polio vaccine was developed much later by Jonas Salk and Albert Sabin.
- (d) Encephalograph is not associated with Roentgen’s discovery.

C)
Transit Control Protocol/ Internet Protocol
D)
Transmission Controlling Protocol/ Internet Protocol
TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is the standard set of protocols used for communication over the internet and other networks.

10^15 is equal to -
A)
5 6
B)
6 5
C)
5 3
D)
6 5
The question text appears to be a formatting issue. Interpreting the options as powers, the intended identity is likely that 10^15 is written in a particular form among the options. However, as displayed, the options are incomplete/garbled and do not clearly show the full expressions. Because of this, the exact correct option cannot be determined with high confidence from the provided text alone.
The present worth of Rs 9900 due 1 year hence at 10% p.a. compounded annually is -
A)
Rs. 9000
B)
Rs. 9100
C)
Rs. 9800
D)
Rs. 10000
For present worth under compound interest, use PV = FV / (1 + r)^n. Here FV = 9900, r = 10% = 0.10, and n = 1 year. So PV = 9900 / 1.1 = 9000. Hence the correct answer is Rs. 9000. The other options do not match this calculation.
A can do a piece of work in 15 days and B can do it in 20 days. If they work together for 6 days, then the remaining work is -
A)
7/60
B)
3/10
C)
6/7
D)
2/10
A’s 1-day work = 1/15 and B’s 1-day work = 1/20. Together, their 1-day work = 1/15 + 1/20 = 7/60. In 6 days, they complete 6 × 7/60 = 7/10 of the work. Therefore, remaining work = 1 - 7/10 = 3/10. So the correct remaining work is 3/10, which matches option (b).

In a group of 65 people, 40 like apple, 10 like both apples and bananas. the number of people who like bananas only is -
A)
25
B)
35
C)
50
D)
75
People who like apples = 40, and among them 10 like both apples and bananas. So, apples only = 40 - 10 = 30. If the total group is 65 and the intended question asks for bananas only, then bananas only = total people - apples only - both = 65 - 30 - 10 = 25. However, this does not match the given options with the wording provided. The only option that fits the usual intended interpretation in such questions is 50, obtained if the question meant 'people who like bananas' as 40 - 10 + 20 etc., but that is not mathematically consistent. The question appears ambiguous/possibly misprinted.
