Answer the questions based on the following information. The following bar chart gives the growth percentage in the number of households in the middle, upper-middle and high-income categories in the four regions for the period between 1987-88 and 1994-95. 


(Number of households in thousands)

Question 11

The ratio of total income for the high-income category to the upper-middle class increased by how much percentage in the given period (approximately) ?


Since we do not know the region-wise population of 1987-1988, we cannot find the increase in the number of households.
Hence, we cannot find the total income for the year 1995-96.
So the ratio cannot be determined.
