To find the effective profit/loss percentage, we need to calculate the total cost price and total selling price for both articles. We'll assume a convenient cost price for the first article to simplify calculations, then determine the selling price of the first article and the cost price of the second article based on the given conditions. Finally, we calculate the selling price of the second article and then the overall profit/loss percentage.
Let the Cost Price of the first article be \( \text{CP}_1 = ₹100 \).
The first article is sold for a 20% profit.
\[ \text{Profit}_1 = 20\% \text{ of } \text{CP}_1 = 0.20 \times ₹100 = ₹20 \]\[ \text{SP}_1 = \text{CP}_1 + \text{Profit}_1 = ₹100 + ₹20 = ₹120 \]The selling price of the first article equals the cost price of the second article.
\[ \text{CP}_2 = \text{SP}_1 = ₹120 \]The second article is sold for a 20% loss.
\[ \text{Loss}_2 = 20\% \text{ of } \text{CP}_2 = 0.20 \times ₹120 = ₹24 \]\[ \text{SP}_2 = \text{CP}_2 - \text{Loss}_2 = ₹120 - ₹24 = ₹96 \]The total cost price for both articles is:
\[ \text{Total CP} = \text{CP}_1 + \text{CP}_2 = ₹100 + ₹120 = ₹220 \]The total selling price for both articles is:
\[ \text{Total SP} = \text{SP}_1 + \text{SP}_2 = ₹120 + ₹96 = ₹216 \]Since Total SP \( < \) Total CP, there is a loss.
\[ \text{Overall Loss} = \text{Total CP} - \text{Total SP} = ₹220 - ₹216 = ₹4 \]The effective loss percentage is:
\[ \text{Loss Percentage} = \frac{\text{Overall Loss}}{\text{Total CP}} \times 100 \]\[ \text{Loss Percentage} = \frac{₹4}{₹220} \times 100 \]\[ \text{Loss Percentage} = \frac{400}{220} = \frac{40}{22} = \frac{20}{11} \approx 1.818\% \]Approximately 1.8% loss.
A) 1.8% loss is the correct answer, as the calculated effective loss percentage is approximately 1.818%.
The question asks for the definition of the Infant Mortality Rate (IMR). This is a standard demographic indicator used to assess the health and well-being of a population, particularly its maternal and child health services. Understanding the precise age limit and the denominator used in its calculation is key.
Correct Option: B) the number of children who die before the age of one year as a proportion of 1000 live children born in that particular year
The question asks about the regional affiliation of the religious teacher Miyan Mir during the 17th century. To answer this, one needs to recall historical facts about prominent Sufi saints and their geographical origins or centers of activity.

Which of the following states is NOT governed by 6th schedule of Indian Constitution?
The question asks to identify the state that is NOT governed by the Sixth Schedule of the Indian Constitution. This requires knowledge of the states covered under the Sixth Schedule, which deals with the administration of tribal areas.
A) Arunachal Pradesh is not covered under the Sixth Schedule of the Indian Constitution. The tribal areas in Arunachal Pradesh are administered under other constitutional provisions, primarily the Fifth Schedule, or general laws, but not the specific autonomous district councils framework of the Sixth Schedule.
When was the International Human Rights Commission established in Geneva?

24th December, 2003
The question asks for the establishment date of the International Human Rights Commission in Geneva. This requires knowledge of specific dates related to international human rights bodies.
Correct Option: D) 24 th December, 2003
To find the percentage change in the area of a square when its side is increased by a certain percentage, we first define the initial side and area. Then, we calculate the new side after the percentage increase and subsequently the new area. Finally, we use the formula for percentage change to determine the overall change in area.
Define initial side and area:
Let the original side of the square be \(a\).
The original area of the square will be \(A_1 = a^2\).
Calculate the new side:
The side is increased by 20%. This means the new side will be the original side plus 20% of the original side.
\[ \text{New side} = a + 20\% \text{ of } a \]\[ \text{New side} = a + \frac{20}{100}a \]\[ \text{New side} = a + 0.20a \]\[ \text{New side} = 1.20a \]Calculate the new area:
The new area \(A_2\) will be the square of the new side.
\[ A_2 = (1.20a)^2 \]\[ A_2 = (1.20)^2 \times a^2 \]\[ A_2 = 1.44a^2 \]Calculate the percentage change in area:
The formula for percentage change is:
\[ \text{Percentage Change} = \frac{\text{New Value} - \text{Original Value}}{\text{Original Value}} \times 100\% \]\[ \text{Percentage Change} = \frac{A_2 - A_1}{A_1} \times 100\% \]Substitute the values:
\[ \text{Percentage Change} = \frac{1.44a^2 - a^2}{a^2} \times 100\% \]\[ \text{Percentage Change} = \frac{(1.44 - 1)a^2}{a^2} \times 100\% \]\[ \text{Percentage Change} = \frac{0.44a^2}{a^2} \times 100\% \]\[ \text{Percentage Change} = 0.44 \times 100\% \]\[ \text{Percentage Change} = 44\% \]Therefore, the percentage change in its area is 44%.
Correct Option: B) 44%
The question asks about the technology used by China for its 'artificial sun'. This refers to experimental devices designed to replicate the energy generation process of the Sun. We need to identify which nuclear process powers the Sun and is being mimicked in these experimental reactors.
Correct Option: D) Nuclear fusion is the process where light atomic nuclei (like hydrogen isotopes) combine under extreme heat and pressure to form a heavier nucleus, releasing a large amount of energy. This is the process that powers the Sun and is what experimental reactors like China's 'artificial sun' (EAST tokamak) aim to replicate for clean energy production.
