Additional Information

  • The rate of personal income tax varies based on income slabs and is progressive in nature, meaning higher income earners pay a higher percentage in taxes.
  • Corporate income tax:
  • This is a tax imposed on the net income or profit of corporations.
  • It is a significant source of revenue for the government and is also a direct tax.
  • Value-added tax (VAT):

  • Consumers ultimately bear the cost of VAT as it is included in the purchase price of goods and services.
  • Non-tax revenue sources:
  • These include all government revenue sources that do not fall under the category of taxes.
  • Examples include fees for services, fines and penalties, dividends from public enterprises, interest receipts, and revenue from government properties.

Why this answer is correct

The correct answer is Turkey.

Key Points

  • The decision aligns with Turkey's foreign policy interests, especially concerning its support for Pakistan and its stance on issues like Kashmir.
  • Turkey has been critical of India's policies in the region, particularly its actions in Jammu and Kashmir, often voicing concerns on international platforms such as the United Nations General Assembly.
  • This ban reflects the broader geopolitical tensions between India and Turkey, which have grown over the years due to differences in their regional and international stances.

Additional Information

  • Turkey's Foreign Policy:

  • Its foreign policy prioritizes its strategic interests, often taking positions that challenge India's regional influence.
  • Turkey is also a member of organizations like the Organization of Islamic Cooperation (OIC), which has occasionally criticized India’s stance on Kashmir.
  • India-Turkey Relations:
  • India-Turkey relations have been strained in recent years, especially after Turkey's vocal criticisms of India's abrogation of Article 370 in Jammu and Kashmir in August 2019.
  • Despite tensions, both countries have bilateral trade relations, although defence cooperation has been severely impacted by the ban.
  • Impact of the Ban:
  • India has diversified its defence imports, relying on countries like Russia, the United States, Israel, and France for military equipment.
  • The ban from Turkey has limited implications for India’s defence sector, as Turkey has not been a major defence supplier to India.
  • Turkey’s Defence Industry:
  • Turkey has a growing defence industry, producing items like drones, tanks, and firearms, which are exported globally.
  • Its defence exports are focused on regions like the Middle East, Africa, and Central Asia.

Important Points

  • Geopolitical Tensions:
  • The ban by Turkey is influenced by broader geopolitical rivalries and regional politics involving India, Pakistan, and other countries.
  • Turkey's stance reflects its strategic alignment with Pakistan, impacting its relations with India.
  • India's Diversification in Defence Imports:
  • India has focused on reducing reliance on specific countries for defence imports by promoting its indigenous defence manufacturing under initiatives like Make in India.
  • India continues to strengthen its defence partnerships with nations such as the United States, France, and Israel to counter such bans.
  • Turkey’s International Relations:
  • Turkey’s foreign policy often reflects its aspirations to emerge as a regional power, balancing its relations with Western countries, Russia, and Islamic nations.

View answer & explanation

Correct answer

Answer: (d)D.

1100

Concept:

Venn Diagram

Calculation:

Suppose x% girls preferred both coffee and smoking.

Girls preferred only coffee = (46 – x)%

Girls preferred only smoking = (15 – x)%

Girls preferred neither coffee nor smoking = 44%

⇒ (46 – x)% + (15 – x)% + 44% + x% = 100%

⇒ 105% - x% = 100%

⇒ x = 5

∴ 5% → 55

⇒ 1% → 11

⇒ 100% → 1100

∴ The total number of girls who participated in survey = 1100
