in a city, 12% of households earn less than rs. 30,000 per year, 6% households earn more than c 2,00,000 per year, 22% households earn more than rs. 1,00,000 per year and 990 house-holds earn between rs. 30,000 and rs. 1,00,000 per year. how many households earn between rs. 1,00,000 and rs. 2,00,000 per year

Answer:

  • Households that earn more than Rs 1,00,000 per year = 22%

  • Households that earn more than Rs 2,00,000 per year = 6%

  • So, Households that earn between Rs 1,00,000 and Rs 2,00,000 per year = 22 - 6 = 16%

  • Now, Households that earn less than Rs. 30,000 per year = 12%

  • Households that earn between Rs 30,000 and Rs 1,00,000 per year = 100 - (22 + 12) = 66% = 990

  • So, 100% = 990 × (100/66) = 1500 So, households that earn between Rs 1,00,000 and Rs 2,00,000 per year = 16% = (16/100) × 1500 = 240
