The question asks for the definition of a "carbon credit." To answer this, we need to understand the concept of carbon trading and its role in environmental policy.
B) It is a credit awarded to the institution based on the carbon emissions allowed and the carbon emissions actually emitted. It can also be traded.
This option accurately describes a carbon credit. It highlights that credits are given based on emission performance (allowed vs. actual) and that they are tradable, which is a fundamental aspect of carbon markets.
Prachi takes Rs. 550 at 5% simple interest per annum. After 4 years, how much money will she have to pay?
To find the total amount Prachi has to pay back, we need to calculate the simple interest accrued over 4 years and then add it to the principal amount she borrowed. The formula for simple interest is \(I = \frac{P \times R \times T}{100}\), where \(P\) is the principal, \(R\) is the rate of interest, and \(T\) is the time.
Using the formula \(I = \frac{P \times R \times T}{100}\):
\[ I = \frac{550 \times 5 \times 4}{100} \]\[ I = \frac{550 \times 20}{100} \]\[ I = \frac{11000}{100} \]\[ I = 110 \]The total amount is the sum of the principal and the simple interest.
\[ \text{Amount} = \text{Principal} + \text{Interest} \]\[ \text{Amount} = 550 + 110 \]\[ \text{Amount} = 660 \]So, Prachi will have to pay Rs. 660 after 4 years.
Correct Option: C) 660
We are given two scenarios where an item is sold at different profit percentages, and the difference in their selling prices is known. We need to find the ratio of these two selling prices. We can assume a cost price for the item, calculate the selling prices for each profit percentage, and then find their ratio.
A) 52 ∶ 55 is the correct ratio of the selling prices when the item is sold at 4% profit and 10% profit, respectively.
Answer the next 3 Questions.
Comprehension:
Direction: Read the given information carefully and answer the following questions. In the following figure, the smaller rectangle represents those who know French, the triangle represents those who know Chinese, the larger rectangle represents those who know Turkish, and the circle represents those who know Odia. The numbers in the different regions show the number of people.
SubQuestion No: 1
How many people can speak both French and Odia?
To determine how many people can speak both French and Odia, we need to identify the overlapping region between the smaller rectangle (French) and the circle (Odia) in the given diagram.
Correct Option: C) 7
SubQuestion No: 2
How many people can speak French only?
The problem asks to determine the number of people who speak French only, based on a Venn diagram (implied, as this is a common type of question for such data). We need to identify the region in the Venn diagram that represents individuals speaking only French, without speaking any other language mentioned.
B) 12 — This option represents the number of people who speak French only, as derived from the specific region in the (unseen) Venn diagram that corresponds to French speakers who do not speak any other language.
SubQuestion No: 3
How many people can speak both Chinese and Turkish?
The problem asks us to find the number of people who can speak both Chinese and Turkish. This is a Venn diagram problem where we need to identify the intersection of the sets representing Chinese speakers and Turkish speakers.
Pointing to a man in a photo, Rani (a girl) said, "His mother's only daughter is my mother." How is Rani related to the man?
This is a blood relation problem. We need to break down the statement made by Rani step-by-step to understand the relationship between the man in the photo and Rani.

Calculate 26064 ÷ 543 ÷ 8.
The problem requires us to perform a series of division operations. We need to follow the order of operations from left to right. First, divide 26064 by 543, and then divide the result by 8.
C) 6 is the correct answer because \(26064 \div 543 = 48\), and then \(48 \div 8 = 6\).
