The question asks to identify the largest tiger reserve park in India as of 2022. This requires knowledge of the area and location of major tiger reserves in India.
The Nagarjunsagar-Srisailam Tiger Reserve is known to be the largest tiger reserve in India, spanning parts of Telangana and Andhra Pradesh.
C) Nagarjunsagar-Srisailam Tiger Reserve, Telangana & Andhra Pradesh is the largest tiger reserve in India, covering an area of approximately 3,728 square kilometers (core area 1,200 sq km and buffer area 2,528 sq km). It is spread across five districts in Telangana and Andhra Pradesh.
When a train crosses a pole, the distance covered by the train is equal to its own length. We are given the time taken by two trains to cross a pole and the relationship between their lengths. We need to find the ratio of their speeds. We will use the formula: \(\text{Speed} = \frac{\text{Distance}}{\text{Time}}\).
Convert time to seconds:
Define lengths:
Express speeds:
Find the ratio of speeds:
We need to find \(S_M : S_N\).
\[ \frac{S_M}{S_N} = \frac{\frac{L_M}{30}}{\frac{L_N}{105}} = \frac{L_M}{30} \times \frac{105}{L_N} \]Substitute the relationship between lengths:
Substitute \(L_M = \frac{1}{2} L_N\) into the ratio expression:
\[ \frac{S_M}{S_N} = \frac{\frac{1}{2} L_N}{30} \times \frac{105}{L_N} \]\[ \frac{S_M}{S_N} = \frac{1}{2 \times 30} \times 105 \]\[ \frac{S_M}{S_N} = \frac{105}{60} \]Simplify the ratio:
Divide both numerator and denominator by their greatest common divisor, which is 15:
\[ \frac{S_M}{S_N} = \frac{105 \div 15}{60 \div 15} = \frac{7}{4} \]So, the ratio of the speed of train M to that of train N is \(7 : 4\).
Correct Option: B) 7 : 4
This is a logical reasoning problem involving ranking based on given conditions. We need to deduce the relative scores of six friends (A, B, C, I, J, K) to find who scored the least. We will use inequalities to represent the scoring relationships and combine them to form a complete order.
To find the average of prime numbers between 11 and 30, we first need to identify all prime numbers in this range. Then, we sum these prime numbers and divide the sum by the count of these prime numbers.
B) 20.2 is the correct average of the prime numbers between 11 and 30.
Study the given graph and answer the question that follows.
The graph presents total sales (in Rs crore) of three companies over six years.
For which of the given pairs of years are the total sales of all three companies together equal?
2011 and 2013
2015 and 2012
2013 and 2016
2011 and 2015
To find which pairs of years have equal total sales for all three companies, we need to calculate the sum of sales for each year and compare them.
Let's calculate:
Comparing the totals:
Correct Option: A) 2011 and 2013
The question asks about how the general public living near the Ganga River can participate in the Namami Gange Programme. This program aims to clean and rejuvenate the Ganga River. Public participation is crucial for its success, especially in preventing pollution at its source.
B) By stopping open defecation on river banks — Open defecation is a major source of fecal contamination and bacterial pollution in rivers like the Ganga. By ceasing this practice, the public directly contributes to improving the water quality and reducing health hazards, which is a core objective of the Namami Gange Programme.
The correct formula for electric power is:
The question asks for the correct formula for electric power. We need to recall the fundamental definition of electric power in terms of voltage and current.
Correct Option: C) P = V.I
This formula correctly represents electric power as the product of voltage and current.
