To find the next number in the series, we need to identify the pattern or rule that governs the sequence of numbers provided. We will examine the relationship between consecutive terms.
Correct Option: A) 95
The question asks to identify the longest railway tunnel in India as of 2017. This requires knowledge of major railway infrastructure projects and their completion status and length at that specific time.
Correct Option: B) Pir Panjal Tunnel
The Pir Panjal Railway Tunnel, also known as the Banihal-Qazigund Railway Tunnel, is approximately 11.215 km long. It was inaugurated in 2013 and was the longest railway tunnel in India as of 2017. It connects Banihal and Qazigund in the Pir Panjal range of the Himalayas.
To determine the shortest person, we need to establish the relative heights of all individuals mentioned. We will use inequalities to represent the height relationships and then combine them to form a complete ordered list from tallest to shortest.
Correct Option: D) Geetha is the shortest among the given people.
The question asks for the definition of a Red Data Book, also known as a Red List. This is a fundamental concept in environmental science and conservation, often covered in general knowledge and environmental studies sections of competitive exams.
Correct Option: D) Document detailing rare and endangered species of animals, plants etc.
The Red Data Book (or IUCN Red List) is a comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. It lists species that are rare, threatened, or endangered, including animals, plants, fungi, and even some forms of protists.
We are given the principal amount, the amount after a certain period, and the time duration. We need to find the annual rate of interest when compounded annually. We will use the compound interest formula to set up an equation and solve for the rate of interest.
The formula for compound interest is:
\[ A = P \left(1 + \frac{R}{100}\right)^n \]where \(A\) is the amount, \(P\) is the principal, \(R\) is the rate of interest per annum, and \(n\) is the number of years.We have \(A = 11664\), \(P = 10000\), and \(n = 2\). Let \(R\) be the rate of interest.
\[ 11664 = 10000 \left(1 + \frac{R}{100}\right)^2 \]Divide both sides by 10000:
\[ \frac{11664}{10000} = \left(1 + \frac{R}{100}\right)^2 \]\[ 1.1664 = \left(1 + \frac{R}{100}\right)^2 \]To find \(\left(1 + \frac{R}{100}\right)\), take the square root of 1.1664:
\[ \sqrt{1.1664} = 1 + \frac{R}{100} \]\[ 1.08 = 1 + \frac{R}{100} \]Subtract 1 from both sides:
\[ 1.08 - 1 = \frac{R}{100} \]\[ 0.08 = \frac{R}{100} \]\[ R = 0.08 \times 100 \]\[ R = 8 \]The rate of interest per annum is 8%.
D) 8.0 is the correct rate of interest per annum.
To find the difference between the smallest five-digit number and the greatest four-digit number, we first need to identify these two numbers and then subtract the smaller from the larger.
Correct Option: D) 1
The question asks for the location of the National Geophysical Research Institute (NGRI). This is a factual question requiring knowledge of the locations of prominent scientific research institutions in India.
Correct Option: B) Hyderabad is the correct location for the National Geophysical Research Institute (NGRI).
The question asks to identify the English County cricket team for which Sachin Tendulkar played. This is a factual question related to the career of a famous cricketer.
C) Yorkshire - Sachin Tendulkar played for Yorkshire County Cricket Club in 1992, becoming their first overseas player.
The question asks to identify which of the given options is NOT a plant product. We need to examine each option and determine its origin.
Correct Option: D) Honey is not a plant product. It is an animal product, specifically produced by bees, although its primary raw material (nectar) comes from plants.
This question asks about the relative abundance of elements in the Earth's crust. To answer this, one needs to recall the general composition of the Earth's crust by mass percentage.
Correct Option: C) Silicon
