A man has two sons. Each son has the same number of brothers and sisters. The man himself has one brother and three sisters. How many children are there in total?
सही उत्तर: क) 4
Let 'x' be the number of children. Each son has x-1 brothers and sisters. Since each son has the same number of brothers and sisters, we can say that the sons have ‘y’ brothers & sisters. This implies: y = x - 1 . Also knowing a man himself has one brother and three sisters, so the total children are x = (one brother + three sisters) + two sons = 6. Thus x=6.

If the sequence is: 1, 3, 5, 7, 9… what is the next term?
सही उत्तर: क) 11
This is a simple arithmetic progression where each term increases by 2. Therefore, the next term in the sequence is 11.

A farmer has chickens and cows. He has a total of 20 animals and 70 legs. How many chickens does he have?
सही उत्तर: ख) 10
This is a classic word problem involving algebra. Let 'c' be the number of chickens and 'w' be the number of cows. We have two equations: c + w = 20 (total animals) and 2c + 4w = 70 (total legs). Solving this system, we find c = 10. The other options are incorrect as they don’t satisfy both equations.

The addition of a small amount of potassium iodide (KI) to a solution containing silver nitrate (AgNO₃) results in the formation of a pale yellow precipitate. What is the primary reason for this observation?
सही उत्तर: ख) The reaction is exothermic and generates heat that causes light emission
This demonstrates the formation of a complex ion [AgI], which is weakly coloured in dilute solutions. The other options are incorrect or do not explain the pale yellow colour.

What is the major product formed when propanal (CH₃CHO) reacts with sodium hydroxide (NaOH)?
सही उत्तर: ग) 1-propanol
The reaction of an aldehyde with a base like NaOH proceeds via nucleophilic addition followed by protonation, resulting in the formation of a primary alcohol (1-propanol). The other options are incorrect products of this specific reaction.

Which of the following statements best explains why NaCl is soluble in water?
सही उत्तर: ख) NaCl forms strong ion-dipole interactions with water molecules
The high dielectric constant of water allows it to effectively stabilize the dissolved ions through strong ion-dipole interactions, overcoming the lattice energy of NaCl. The other options describe inaccurate or irrelevant effects.

The process of converting primary alcohols to aldehydes using mild alkali metal hydrides like NaBH₄ is called ______.
सही उत्तर: क) Reduction
This describes the selective reduction of alcohols to aldehydes. The other options represent fundamentally different chemical processes (ester formation, breaking ester bonds, and oxidation respectively).

Which of the following cellular structures is MOST directly involved in the process of aerobic respiration generating ATP?
सही उत्तर: ग) C) Mitochondria – Containing the electron transport chain.
The mitochondria are the powerhouse of the cell. They contain the inner membrane where the electron transport chain operates, which is crucial for generating ATP (adenosine triphosphate), the primary energy currency of cells, through aerobic respiration.

In mammals, which hormone is primarily responsible for maintaining calcium homeostasis and regulating bone mineralization?
सही उत्तर: ख) B) Parathyroid Hormone (PTH) – Increasing blood calcium levels.
Parathormone (PTH), secreted by the parathyroid glands, plays a central role in maintaining proper blood calcium levels. It achieves this primarily by stimulating bone resorption (releasing calcium into the bloodstream), increasing calcium reabsorption in the kidneys, and enhancing calcium absorption from the intestines,

Which of the following best describes the role of the myelin sheath in nerve impulse transmission?
सही उत्तर: ख) B) It insulates the axon, allowing for faster signal propagation.
The myelin sheath, formed by glial cells (Schwann cells in peripheral nerves and oligodendrocytes in central nerves), acts as an insulator around the axon of a neuron. This insulation significantly speeds up the transmission of nerve impulses by allowing for ‘saltatory conduction’ – where the signal jumps between gaps in the myelin, preventing constant friction.
