Sample questions from Mock 16 with answers
10 of the 180 questions, with answers and explanations. The rest are in the app.
Question 1
Biology · Reproductive HealthMedical termination of pregnancy (MTP) is considered comparatively safe up to about:
- A 4 weeks
- B 12 weeks
- C 28 weeks
- 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 CirculationThe condition in which the heart is not pumping the blood effectively enough to meet the needs of the body is called:
- A a heart attack
- B heart failure (congestive heart failure)
- C an angina
- D a cardiac arrest
Answer: B. heart failure (congestive heart failure)
Why: The lungs may get congested.
Question 3
Biology · Reproductive HealthA population in which the number of births exceeds the number of deaths shows:
- A growth in the population size
- B a fall in the population
- C extinction
- 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 PlantsA typical anther is tetrasporangiate, which means that it has:
- A four petals
- B four ovules
- C four microsporangia (pollen sacs)
- 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 PlantsIn the stems, the primary xylem is:
- A endarch, with the protoxylem towards the pith
- B with metaxylem in the centre
- C scattered
- D exarch
Answer: A. endarch, with the protoxylem towards the pith
Why: In the roots, the xylem is exarch.
Question 6
Physics · Laws of MotionTwo 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:
- A 1 m/s²
- B 10 m/s²
- C 5 m/s²
- 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 SolidsThe elastic limit of a material is the maximum stress beyond which:
- A the material returns to its original shape upon removal of the load
- B the material does not fully regain its original shape after the load is removed
- C the material becomes a superconductor
- 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 HaloarenesThe correct order of the boiling points of the alkyl halides RF, RCl, RBr and RI (same alkyl group) is:
- A all are equal
- B RCl < RF < RI < RBr
- C RF < RCl < RBr < RI
- 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 ChemistryThe species :CH₂ (methylene or carbene) has:
- A eight electrons
- B six electrons in the valence shell of carbon, and no charge
- C a positive charge
- 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 KineticsThe decomposition of N₂O₅ is first-order. If the half-life is 24 minutes, the rate constant is about:
- A 2.9 min⁻¹
- B 0.29 min⁻¹
- C 0.029 min⁻¹
- D 0.0029 min⁻¹
Answer: C. 0.029 min⁻¹
Why: k = 0.693/24.
