The first and second groups of the modern periodic table are called s-block. Key Points The periodic table, also known as the periodic table of elements, is a tabular display of chemical elements. The s-block elements of the periodic table are those in which the last electron enters the outermost s-orbital. Since the s-orbital can only accommodate two electrons, the two groups (1 and 2) belong to the s- block of the periodic table. Alkali metals are called s block because they form alkalis when they react with water. Alkalis, including sodium hydroxide and potassium hydroxide, are hydroxide compounds of these elements. Additional Information Block Groups Group 1 (alkali metals) and Group 2 (alkaline earth metals) plus Period 1 s (hydrogen and helium) d Groups 3 to 12 (transition metals) p Groups 13 to 18 (includes all Noble Gases, halogens and chalcogens) f Lanthanoids and Actinoids 8. Answer: d Explanation: Given: Number of students opted Mathematics = n(M) = 35 Number of students opted Biology = n(B) = 33  Calculation: The number of students who did not opt these two subjects is, 85 - n(M U B) = 23 n(M U B) = 85 - 23 = 62 n(M U B) is number of students opted mathematics or Biology. n(M ∩ B) is number of students opted both mathematics and Biology. The formula is:- n(M U B) = n(M) + n(B) - n(M ∩ B) 62 = 35 + 33 - n(M ∩ B) n(M ∩ B) = 68 - 62 = 6 6 students opted for both Mathematics and Biology subjects. Hence, "option 4" is the correct answer. 9. Answer: d Explanation: The correct answer is pressure. Nm –2 is the international (SI) unit of pressure. Key Points  The International System of Units (SI) is the basis of the modern metric system. All SI units can be derived from the seven fundamental SI units. Pressure, in the physical sciences , is the perpendicular force per unit area, or the stress at a point within a confined fluid. Pressure is the force per unit perpendicular area over which the force is applied, p = F/A. Pressure is defined as force applied per unit area. Hence, its SI unit is N/m 2or Pascal here, 1 Pascal = 1 N/m 2. Additional Information Pressure is classified into three types, they are: Absolute pressure. Gauge pressure. Differential pressure. Sealed pressure or vacuum pressure. Important Points Unit of SI Unit force Newton (N) thrust Newton (N) momentum kg⋅m/s 10. Answer: d Explanation: Given: Person 1 is moving at a speed of 5.4 kmph i.e. 3/2 mps Person 2 is moving at a speed of 6 kmph i.e. 5/3 mps The mini-van crosses them in 4.5 sec and 6.75 sec respectively. Concept used: When a mini-van crosses a person, it basically crosses its own length. The relative speed when two objectives are moving in the same direction is the positive difference between their individual speeds. Distance = Time × Speed Kilometer per hour (kmph) = 3.6 × Meter per second (mps) Calculation: Let the speed & length of the mini-van be S mps & L meter. According to the question, (S - 3/2) × 4.5 = L; (S - 5/3) × 6.75 = L; So, (S - 3/2) × 4.5 = (S - 5/3) × 6.75 ⇒ (S - 3/2) × (9/2) = (S - 5/3) × (27/4) ⇒S=2 So, the speed of the mini-van, S = 2 mps Then, the length of the mini-van, L = 2.25 meter ∴ 2.25 meter is the length of the mini-van. 11. Answer: a Explanation: Given: The marked price of the laptop is Rs 22,000. Discount is given 12 1 2 ​ % i.e. (25/2)% VAT is charged at 10% Concept used: Selling Price = Marked Price - Discount Application of percentage Calculation: So, the selling price after discount = 22500 - (22500 × (25/200)) = Rs. 19250 Then, the final selling price after adding a VAT on it = (19500 × 1.1) = Rs. 21,175 ∴ The customer will have to pay Rs. 21,175 for the laptop. Shortcut Trick Here comes the successive percentage calculation. One discount of 12.5% is given & 10% VAT was charged after that. So, final percentage change = -12.5 + 10 - {(12.5 × 10) ÷ 100} = -3.75 So, the final selling price of the laptop = {22000 × (100 - 3.75)} ÷ 100 = Rs. 21175 ∴ The customer will have to pay Rs. 21,175 for the laptop. 12.

Answer: c Explanation: Given: Hari invested Rs.100 for three years at a simple interest rate of 11.03%. Tipu invested a sum for three years at 10%. Concept used: Simple Interest, SI = (P × R × T) ÷ 100 where P = Principal amount R = Rate of interest per year T = Time in years Compound interest, CI = P(1 + R/100) n - P where P = Principal amount R = Rate of interest per year N = Time in years Calculation: Let the principal amount that Tipu invested be Rs. P. After three years, Hari gets simple interest on the sum he invested, ⇒ (100 × 11.03 × 3) ÷ 100 ⇒ Rs. 33.09 Tipu gets compound interest on the sum he invested, ⇒ {P × (1 + 10/100) 3} - P ⇒ P × 0.331 According to the question, P × 0.331 = 33.09 ⇒ P = 99.969.. ⇒ P ≈ 100 ∴ Tipu should invest Rs. 100 to get the same amount after three years but at 10% compound interest. 18.

Answer: c Explanation: The statement suggests that people should respect the national anthem. Argument I agrees with the statement and justifies that as the citizens of the country, people should show respect and pride by standing upright during the national anthem. There is no loss in standing upright when the national anthem is being played. On the contrary, one may feel a sense of patriotism during the act. So, argument I is strong. Argument II disagrees with the statement suggesting it to be unnecessary patriotism. However, the word "unnecessary" is used without justifying why is it unnecessary or useless. Rather, it can be considered as one of the ways in which patriotism can be cultivated or sustained. Thus, argument II is not strong. Hence the correct answer is option 3. 72. Answer: c Explanation: It is given that Pravalika is in standard 10th. We do not know anything about Pranita from the question statement. Since Pranita is Pravalika's classmate, they could be about the same age. It cannot be determined who is older until we know the age details of both persons. The age details of Pranita and Pravalika are not mentioned in the conclusions. So, none of the conclusions is correct. Hence the correct answer is option 3. 73. Answer: a Explanation: The correct answer is Will decrease. If the humidity in the atmosphere is high, the rate of evaporation is low because the air is filled with water vapor and is not able to take up more humidity. Thus, the evaporation process slows down. Key Points Evaporation is a form of vaporization that usually occurs at the surface of a liquid and involves the transition of liquid particles to the gaseous phase. Therefore, this process is said to involve a change in the state of the fluid. The surrounding gas should not saturate with the substance to be evaporated. The rate of evaporation is greater at higher temperatures because as the temperature rises, the amount of energy required for evaporation decreases. Water loss by evaporation in sunny, warm weather is greater than in cloudy and cool weather. The moisture content of the air, or water vapor content, also has an effect on evaporation. The lower the relative humidity, the drier the air, and the higher the rate of evaporation. The more moist the air, the closer the air is to saturation, and the less evaporation can take place. Also, warm air can have a higher concentration of water vapor, so you might think th
