Data Interpretation Practice Test 1

In these type of problems, where there are two pie-charts, for two years, and the latter year has a much higher total (as here, Rs 10.4 lakhs in 1986 and Rs 103 lakh in 1996). In general, the smallest segment will have the smallest growth, in rupees, and the largest segments will have the largest growth, in spite of how the actual percentages change. In other words, because social security and insurance here is the smallest item, it is the best place to start. Nine per cent of 10 lakhs of rupees is 0.9 lakh in 1986. 7.3% of Rs 103 lakhs is about 7.5 lakhs in 1996, for an increase of about 6.6 lakhs. Allocations were 16% in 1986, or 1.6 lakhs, and 10% in 1996 or 10.4 lakhs, an increase of about 8.8 lakhs. Social security and insurance had a smaller increase, and the other items are not worth checking. Note that allocation went from 16% in 1986 to 10% in 1996, a greater decrease in percentage than social security and insurance, which went from 9% to 7%, but this did not matter.
