Correct option (b) 240
Explanation:
According to the question:Households that earn more than Rs1,00,000 per year =22% and households that earn more than Rs 2,00,000 per year = 6%
Hence, 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
Hence, households that earn between Rs 1,00,000 and Rs 2,00,000 per year = 16% = (16/100) × 1500 = 240
