The question asks for the common name of elements in the f-block of the periodic table. This requires knowledge of the classification of elements based on their electronic configuration and position in the periodic table.
Correct Option: C) Inner transition element — The f-block elements (lanthanides and actinides) are characterized by the filling of the \((n-2)f\) orbitals and are located within the d-block elements, hence they are called inner transition elements.
The question asks to identify the statement that is NOT true about alkalis. We need to evaluate each given option based on the known properties of alkalis.

This statement is incorrect because alkalis (bases) turn red litmus paper blue, not blue litmus paper red. Acids are the substances that turn blue litmus paper red.
The amount of Rs 66300 is divided between Ram and John in such a way that Ram's share after 6 years is equal to John's share after 4 years. The interest for both Ram and John is 10% compounded annually. What will be their shares (Rs.)?
30,000, 36,300
20,000, 46,300
32,000, 34,300
10,000, 56,300
This problem involves dividing a sum of money between two individuals such that their future values, compounded annually at a given interest rate, are equal after different time periods. We will use the compound interest formula to set up an equation relating their initial shares and then solve for the individual shares.
Let the total amount be \(P = \text{Rs } 66300\).
Let Ram's share be \(R\) and John's share be \(J\). We know that \(R + J = 66300\).
The interest rate is \(r = 10\%\) compounded annually, which is \(0.10\) in decimal form.
Ram's share after 6 years will be \(R(1 + r)^6\).
John's share after 4 years will be \(J(1 + r)^4\).
According to the problem, Ram's share after 6 years is equal to John's share after 4 years:
\[ R(1 + r)^6 = J(1 + r)^4 \]Substitute the value of \(r\):
\[ R(1 + 0.10)^6 = J(1 + 0.10)^4 \]\[ R(1.1)^6 = J(1.1)^4 \]Divide both sides by \((1.1)^4\):
\[ R(1.1)^2 = J \]\[ R(1.21) = J \]Now we have two equations:
Substitute equation (b) into equation (a):
\[ R + 1.21R = 66300 \]\[ 2.21R = 66300 \]Solve for \(R\):
\[ R = \frac{66300}{2.21} \]\[ R = 30000 \]Now find John's share \(J\):
\[ J = 1.21R \]\[ J = 1.21 \times 30000 \]\[ J = 36300 \]So, Ram's share is Rs 30,000 and John's share is Rs 36,300.
Correct Option: A) 30,000, 36,300
To determine the overall profit or loss, we need to calculate the Cost Price (CP) of both the horse and the cow. We are given their Selling Price (SP) and the profit/loss percentage for each. Once we have the CPs, we can find the total CP and total SP to calculate the net profit or loss.
Correct Option: C) Profit of Rs. 666.67
The question asks to identify who among the given options has served as the Speaker of the Lok Sabha. This requires knowledge of prominent political figures and their roles in Indian parliamentary history.

The problem requires selecting a team of five people from a given pool of boys and girls, subject to several selection criteria. We are given that Abhinav and Chirag are already selected members, and we need to find the remaining three members from the given options. We will systematically apply all the given conditions to eliminate incorrect options and identify the correct one.
Initial Selection: Abhinav (B) and Chirag (B) are already selected. This means 2 members are chosen, and 3 more need to be selected to form a team of 5.
Apply Condition (iv): "Chirag and Jawahar are to be kept together." Since Chirag is selected, Jawahar (B) must also be selected. Now, the selected members are Abhinav, Chirag, Jawahar. We need 2 more members.
Apply Condition (i): "Abhinav and Shanti have to be put together." Since Abhinav is selected, Shanti (G) must also be selected. Now, the selected members are Abhinav, Chirag, Jawahar, Shanti. We need 1 more member.
Current Team: Abhinav (B), Chirag (B), Jawahar (B), Shanti (G).
Remaining Pool:
We need to select 1 more member from this remaining pool.
Evaluate Options based on current team and remaining conditions:
Condition (ii): "Deva and Kirtana cannot be kept together."
Condition (iii): "Preeti cannot be placed along with Rekha."
Condition (v): "Rekha cannot be placed with Hitesh."
A) Hitesh, Jawahar, Shanti
B) Preeti, Rekha, Deva
C) Preeti, Kirtana, Jawahar
D) Shanti, Kirtana, Preeti
The question asks for the name of the two-layered membrane covering the heart. This is a direct knowledge-based question related to human anatomy, specifically the cardiovascular system. We need to identify the correct anatomical term for this protective covering.
