Solved Questions for You

Question 1: A country that has a constitution must be a democracy.

  1. True
  2. False

Answer:  A country that is a democracy must have a constitution.

Question 2: What are the advantages of having a healthy population?

Answer: The advantages of having a healthy population are:

  • A healthy individual is much more efficient and productive than an unhealthy individual.
  • He or she is able to realize his or her potential and play an important role in social and national development.
  • Absenteeism is low where the workers are healthy.
  • A healthy population helps in building a productive workforce for the country. Even the non-productive age group needs to be healthy to reduce the burden of healthcare.

Question 3: Why are manure and fertilizers used in fields?

Answer: Manure is organic matter derived from animal faeces and plant waste. When the plants are cultivated continuously on a field, the soil gradually loses its nutrient and eventually gets depleted. Thus, manures and fertilizers are used to provide nutrient to the soil due to which the crop yield is enhanced.

Question 4: If x+y+z=0, show that x3+y3+z3=3xyz.

Answer: We know that x3+y3+z3−3xyz=(x+y+z)(x2+y2+z2−xyyzzx)

Given x+y+z=0

x3+y3+z3−3xyz=(0)(x2+y2+z2−xyyzzx)

x3+y3+z3−3xyz=0

x3+y3+z3=3xyz

Hence proved.
