10 of the 180 questions, with answers and explanations. The rest are in the app.

Question 1

Biology · Reproductive Health

Medical termination of pregnancy (MTP) is considered comparatively safe up to about:

  1. A 4 weeks
  2. B 12 weeks
  3. C 28 weeks
  4. D 40 weeks

Answer: B. 12 weeks

Why: MTP is considered comparatively safer during the first trimester, up to about 12 weeks of pregnancy.

Question 2

Biology · Body Fluids and Circulation

The condition in which the heart is not pumping the blood effectively enough to meet the needs of the body is called:

  1. A a heart attack
  2. B heart failure (congestive heart failure)
  3. C an angina
  4. D a cardiac arrest

Answer: B. heart failure (congestive heart failure)

Why: The lungs may get congested.

Question 3

Biology · Reproductive Health

A population in which the number of births exceeds the number of deaths shows:

  1. A growth in the population size
  2. B a fall in the population
  3. C extinction
  4. D no change in the population

Answer: A. growth in the population size

Why: The population explosion in India is a concern.

Question 4

Biology · Sexual Reproduction in Flowering Plants

A typical anther is tetrasporangiate, which means that it has:

  1. A four petals
  2. B four ovules
  3. C four microsporangia (pollen sacs)
  4. D four stamens

Answer: C. four microsporangia (pollen sacs)

Why: It is bilobed, and each lobe has two theca.

Question 5

Biology · Anatomy of Flowering Plants

In the stems, the primary xylem is:

  1. A endarch, with the protoxylem towards the pith
  2. B with metaxylem in the centre
  3. C scattered
  4. D exarch

Answer: A. endarch, with the protoxylem towards the pith

Why: In the roots, the xylem is exarch.

Question 6

Physics · Laws of Motion

Two masses of 3 kg and 2 kg are joined by a light string over a smooth pulley (Atwood machine). Taking g = 10 m/s², the acceleration is:

  1. A 1 m/s²
  2. B 10 m/s²
  3. C 5 m/s²
  4. D 2 m/s²

Answer: D. 2 m/s²

Why: a = (m₁ − m₂)g/(m₁ + m₂) = 10/5 = 2 m/s².

Question 7

Physics · Mechanical Properties of Solids

The elastic limit of a material is the maximum stress beyond which:

  1. A the material returns to its original shape upon removal of the load
  2. B the material does not fully regain its original shape after the load is removed
  3. C the material becomes a superconductor
  4. D the material's mass changes

Answer: B. the material does not fully regain its original shape after the load is removed

Why: Beyond the elastic limit, permanent (plastic) deformation occurs — the material no longer fully returns to its original shape when the deforming force is removed.

Question 8

Chemistry · Haloalkanes and Haloarenes

The correct order of the boiling points of the alkyl halides RF, RCl, RBr and RI (same alkyl group) is:

  1. A all are equal
  2. B RCl < RF < RI < RBr
  3. C RF < RCl < RBr < RI
  4. D RI < RBr < RCl < RF

Answer: C. RF < RCl < RBr < RI

Why: The size of the halogen, and the London forces, increase down the group.

Question 9

Chemistry · General Principles of Organic Chemistry

The species :CH₂ (methylene or carbene) has:

  1. A eight electrons
  2. B six electrons in the valence shell of carbon, and no charge
  3. C a positive charge
  4. D a negative charge

Answer: B. six electrons in the valence shell of carbon, and no charge

Why: It is a neutral, divalent and highly reactive species.

Question 10

Chemistry · Chemical Kinetics

The decomposition of N₂O₅ is first-order. If the half-life is 24 minutes, the rate constant is about:

  1. A 2.9 min⁻¹
  2. B 0.29 min⁻¹
  3. C 0.029 min⁻¹
  4. D 0.0029 min⁻¹

Answer: C. 0.029 min⁻¹

Why: k = 0.693/24.
